The best time to invest in crypto has already passed, now prices are not very high, but not the lowest. Now you can invest in top coins because they'll grow even stronger over time...
The top coins will usually go up in value with Bitcoin, but if the market enters a bull phase, all coins available in this market will tend to rise very high. During this time, you should consider carefully because the risk may occur at any time. The bear market has not ended, and the crypto market may once again collapse if there is bad news. This has happened in the past, and it is often a very bad time for all investors here.
