Absolutely , there are thousands of cryptocurrencies in existence and there are Hundreds in TOP rank that we can choose so why need to invest in single coin , also there is Bitcoin that is more safer and better so make it as our priority.
I may want to advise buying Ethereum also because that is what major altcoin means to me , and of course Binance though some news it was risky but for long term , I think I am good in this one.
There were millions actually and over 8k are only left that are still active. Not all are the same. Maybe some are lacking in budget so they can only afford to invest in one coin. Another advantage of it is you will have less stress on managing it. Binance was involved in a SEC issue, and that causes others to doubt about it.
But, just ignore the noise and follow what your heart says. If you believe that Binance will pass all of their troubles and remains to be the top crypto company then go on. Let them regret when that time comes. I wouldn't mind adding that coin as well, then of course ETH because it was like a BTC but only in the altcoin section.
