Yeah i agree that Bitcoin is the best option to invest with but OP is aking for ALTCOIN and obviously this is altcoin section.
So basically it is
ETHEREUM
BINANCE
EOS
and secondary are
Litecoin
Ripple
Your review of that is absolutely correct, as we are on the topic of Altcoin. If the best cryptocurrency investment portfolio is BTC, and with Altcoin i think your list is absolutely correct. Since altcoins have platforms that develop different ways of working, i see nothing, because I always think that the platforms that exist on top CMC are always the most successful.
