I have been observing how cycles repeat in crypto and there is truly a pattern we cannot ignore. Every time we see these extreme price movements—especially when they rise in a parabolic way without clear fundamentals—we are witnessing what economists call a bubble. And yes, crypto bubbles are as real as those we've seen in other markets.

The classic framework of Minsky and Kindleberger describes exactly what happens: displacement, boom, euphoria, profit-taking, and panic. If I think about it, we've seen this complete cycle several times in crypto. The BIS and IMF constantly document it— that boom of 2021-2022 followed by the crash was textbook. International institutions warn about structural risks in DeFi that are supposedly decentralized but actually concentrate risks in ways we don't see at first glance.

Historical cases are clear. The ICO boom in 2017-2018 was brutal—projects raising millions without anything behind them. Many were practically scams. Then came the NFT craze in 2021, where OpenSea and similar platforms exploded in volume only to crash dramatically afterward. That is the bubble dynamic in crypto in action.

How to identify them before they explode? There are clear signals. First, prices shoot up in a parabolic way while real utility indicators lag behind—pure FOMO and narratives of "this time is different." Second, leverage inflates, promising risk-free returns. Third, liquidity disappears in small coins while prices fly. Fourth, you see influencers and celebrities promoting everything, Google searches explode, social media goes crazy. Fifth, information is uneven, new projects without real transparency.

The practical defense is pure discipline. Position size according to volatility— the more volatile, the smaller the exposure. Avoid excessive leverage because when the market reverses, those positions are liquidated quickly. Diversify narratives, don't invest everything in a single idea. Spot ETFs for BTC and ETH are safer channels than speculative altcoins. Truly verify utility, governance, project audits.

And most importantly: exit plan. Profit-taking targets in phases, disciplined stop-loss. Execution is more important than predicting.

The reality is that a crypto bubble is not just prices going up. It is narrative + credit + mass psychology reinforcing each other. Understand Minsky's framework, read the warnings from BIS and IMF, apply serious risk management. That is the way to keep a cool head when euphoria returns.
