For the cryptocurrency market, blind investment is not correct. There is no positive signal now. This may still be a year of bear market. You can wait patiently for months to buy coins. If you are buying Bitcoin, you can buy it now.
It all depends specifically on each coin. The same Ethereum fell for a long time, and now it began to grow and those who bought it for $ 90 could earn very well. Similarly with many other altcoins. The main thing is to be able to choose coins for investment.
