altcoins is were you get the best returns thats the place to be for that high multiplier returns.
But volume is low if your buying a top 10-20 altcoin I don't see the point might as well just buy bitcoin safer same returns
In my opinion, altcoin still very good to invest if you have good knowledge about choosing potential cryptos. The altcoin is suitable for invest in short-term to get profit quickly. Instead of buying Bitcoin to avoid risk, I think you should consider investing in altcoin like ETH, EOS, XRP because that cryptos is very hot and will make the high profit if the market recover.
Investing in these coins will help you be safe on the market but will not help you earn big profits on all those coins. Everything can easily change quickly and instead of investing in old coins you should choose new coins because the opportunity to bring you profits will be much higher. In fact, to be able to find new potential coins is really difficult because you have to have an evaluation in every project and an infinite source of knowledge to be able to do this.
