I know this Bitcoin has gone up and it's climbing further but is still down more than 50% from its ATH which actually means that we are in the down market. To be honest, whether people say that the down market does not mean it is the end of the world for Bitcoin or anything for that matter. There is historic evidence that the market goes down and then comes back stronger to reach new heights. We have seen that with Bitcoin too, where it reached ATH then went back down and then went up crazy, and this is what the market cycle is all about ups and downs.

But we should not be fearing a down market if the financial goals are not near. The thing is we should only invest in such a volatile market if we have a goals little far away. For short terms goals it is always better to invest in FD or Debt funds. Like Stocks, cryptocurrency is also volatile and thus we start investing in that only for the long term or if the profit is good we can book the profit too.
It's not only about Bitcoin, just see the chart of the US Market where we have seen so many ups and downs in the market. And this is the reason the bear market is best for someone who is investing for the long term. You might not realize it now, but to be honest, when someone keeps investing in the bear market they will get a profit in the future. the XIRR will show some percentage, but the true percentage would be more if you would have invested more amount at the time of the bear market. we can think of it as a sale and thus grab some of the great stuff at a discount.
People would be thinking why not invest in FD when the rate is high, but again even if the stock prices/crypto have fallen they will eventually give a good percentage. But we should only invest as per our risk-taking ability. We do not know when the market can go up but what we know is that it will go up in the future and whoever has been investing in this time will reap the profit in the future. It's not about timing the market, it's about investing at the right time and it is now. But honestly, we can invest any time.
We just have to stick to our plan and thus invest as per our financial situation, but if we can invest more, now is the time.
