Take a look at the BTC weekly chart, it has risen for about four weeks, with the largest gains in these three weeks. According to the 21-year cycle trend, it is basically approaching the top edge. At this stage, liquidity is very poor, and most of it is institutions trading with each other. Personally, I feel that there is basically no need for much investment once this cycle is over. If altcoins have another round of gains, I would basically cash out and no longer need to invest in this circle; decentralization has already become a thing of the past. Retail contracts have resulted in liquidation for both long and short positions, while spot gains are relatively acceptable. We are now at the tail end of investment; the dividends are basically over, and institutions have absolute pricing power. Unless several million silent bitcoins enter the market, it's hard to say otherwise.

If you have suffered significant losses in this cycle, it's better not to enter the market anymore. If you have made a lot of profits in BTC, you can cash out. You can wait a bit for altcoins. Both the US stock bubble and the BTC bubble are quite large, and the economic depression has slowly begun at this stage. It's hard to tell when a financial crisis will hit; once it erupts, it won't be just a minor issue. Don't be greedy, exercise restraint, and look back in four years. If you can't bear to part with it, you can keep a small amount of capital to play around with; if you lose it, it won't hurt too much, and you can gain experience.
