We come to the crypto world to make money, not to gamble, so we must earn certain money safely. What money is the safest? Bitcoin! All your operations in the crypto world should point to one goal: to increase your Bitcoin.

How to earn more Bitcoin?
1. Continue to buy in a bear market;
2. Buy on dips in a bull market: buy a little on small dips, and buy more on large dips; 3. When the bull market is crazy, convert all the profits from altcoins into Bitcoin in a timely manner.
My Polkadot DOT, I didn't sell it in time at its peak, and it dropped 90% in the bear market. If I had sold at the high, I could have waited for the bear market opportunity and exchanged it for two Bitcoins; now it's still in my hands and only worth 0.14 Bitcoins. This is the altcoin world, it really can drop like dog shit. The vast majority of altcoins will go to zero. Bitcoin has dropped, but in the next bull market, it will return as the king.
4. In a bear market, only by holding Bitcoin can one wait calmly for the next bull market. I have even converted all my altcoins into Bitcoin. Holding altcoins is really tough. Even if I make a little money, it's not enough to see a psychologist.
5. In a bull market, Bitcoin will lead the rise, followed by a chaotic flourish of altcoins. At this time, you can buy some altcoins with high circulation, make a profit and quickly run away, and then exchange it for Bitcoin to hold.
