Something many wonder when they hear about blockchain and mining: is it legal to mine Bitcoin? The question is more complex than it seems, especially if we look at what has happened in recent years with blockchain games.

I clearly remember when in 2021 Chinese authorities sharply cracked down on traditional mining. They were right, actually. Bitcoin mining and other cryptocurrencies require specialized hardware, consume huge amounts of energy, and environmental damage is real. But here’s where the confusion begins: when the blockchain gaming trend with the "play to earn" model arrived, many started saying it was the same thing. Spoiler: it’s not.

Let’s bring some order. Traditional virtual currency mining is a mechanism where miners use powerful computers to solve complex mathematical problems, validate transactions, and create new blocks. Whoever does it first receives a reward in Bitcoin or other cryptocurrencies. It’s a process that requires dedicated hardware, consumes a lot of electricity, and that’s why it has been heavily regulated.

Then there’s liquidity mining, which is a completely different beast. It’s not Bitcoin mining in the traditional sense. Here, users provide assets to DeFi protocols to support liquidity and receive governance tokens or fees in return. Let’s take a concrete example: depositing tokens into a lending platform like Compound, improving the pool’s liquidity, and receiving COMP tokens as a reward. There’s no hardware, no massive energy consumption. It’s a token distribution mechanism, period.

Now, blockchain games. Most of these games work like this: you create an account, buy game tokens using cryptocurrency, play (kill monsters, breed digital animals, whatever), accumulate tokens or game items, and then sell them for other cryptocurrencies. Subjectively, players think they’re making money playing. Objectively, what’s happening is they’re providing liquidity to game tokens by exchanging them. It’s similar to liquidity mining, not Bitcoin mining.

A classic example is Mobox, founded in 2020. Their platform is built around liquidity mining via PancakeSwap. Users provide liquidity for Mobox-BNB pairs, get LP tokens, stake them on Mobox, and receive Mbox tokens. It’s all integrated into the game, but the underlying mechanism is pure DeFi.

So, a logical question: does the 2021 ban on Bitcoin and traditional mining also cover blockchain games? No, it doesn’t. Because the ban was specific to energy consumption and the waste of national resources. Bitcoin mining requires enormous amounts of electricity. Blockchain games and liquidity mining do not. They are completely different models from an energy perspective.

But beware, here comes the important part. Just because Bitcoin mining has been regulated and blockchain games are not covered by that ban doesn’t mean blockchain games are completely legally safe. There are other legal risks that developers must seriously consider.

The first is the risk of being considered an illegal casino. If gameplay promises guaranteed earnings, if the mechanics are mainly based on luck rather than skill, if the system is clearly designed to favor those who invested more money initially, then you could find yourself in dangerous territory. Authorities do not distinguish between traditional gambling and digital gambling when the substance is the same.

The second, and perhaps more serious, is the risk of illegal fund-raising. This is not a specific crime, but falls into two main categories: illegal collection of public deposits and fraud in fund-raising.

For illegal collection of public deposits, there are four characteristics authorities look for: illegality, transparency, inducement, and non-specificity. Transparency and non-specificity are present in any blockchain game. You publish the game, attract general users from everywhere, promise rewards. Even if you use invitation codes or participation thresholds, courts do not consider this a real limitation.

Illegality is the critical point. If the blockchain gaming platform allows direct transactions between legal currencies and tokens, or if it acts as a central counterparty in exchanges, it violates regulations on preventing risks of token-based financing. It’s prohibited. So developers must be very careful how they structure the flow of money.

Inducement is the second critical point. If during promotion you promise players they will keep their capital and receive guaranteed interest, or if you promise fixed returns, then you are inducing participation with promises of certain gains. This is a red flag for authorities.

Regarding fraud in fund-raising, the risk is when developers collect funds from players with the intention of appropriating the money, using it for illegal activities, or hiding the funds to avoid returning them. Here, the theoretical decentralization of blockchain doesn’t help much. Yes, blockchain is immutable and transparent, but the reality is that domestic blockchain games are not fully decentralized. Public chains have a certain degree of decentralization, but private chains and alliances do not. Nodes are limited, and in theory, organizers could collaborate with malicious players to harm others.

So, returning to the initial question: is Bitcoin mining legal? The answer is nuanced. Traditional Bitcoin mining has been regulated and limited in many countries due to energy consumption. Blockchain games do not fall under that specific ban because they don’t have the same energy impact. But that doesn’t mean they are completely legal. It depends on how they are structured, how they are promoted, and how they handle the flow of money.

For blockchain game developers, the advice is clear: avoid promising guaranteed earnings, ensure gameplay is not mainly based on luck or the amount of initial capital invested, structure the payment system so it doesn’t violate fundraising regulations, and be transparent about how the game actually works. If you do this, you significantly reduce legal risks.

The bottom line is that Bitcoin mining is one thing, blockchain games are another. Don’t confuse the two, and if you are developing a blockchain gaming platform, make sure to get proper legal advice before launching.
