I think, that it will be the most solid investment, if you will buy tokens from the top 10 or top 20 cryptocurrencies. they will not make such a large growth as new tokens that are now coming on the market, but investing in the top 20 is more reliable
Agree with you on the basis of stability. However the chances of growth my be slim in comparable to investing in low capped or good ico that does well. the question is if it will do well on the long run.
