If you have enough capital, you can invest in some crypto. Half of your capital can be invested in Bitcoin, the other half you share in several altcoins. But what you need to make sure is that the crypto can survive. To me a coin rated 100 CMC has good potential for investment. But some of crypto also experienced big problems.
I will invest assets for Bitcoin and will not diversify for altcoins in low market price conditions, we can review from the fact today's market price that only the dominant Bitcoin price is increasing while altcoins are relatively not increasing and stable, but if you diversify then only 20% will be determined for the choice of investment in altcoins in the top 10 top altcoin choices.
