Personally i dont like altcoins, they are so unpredictable and a waste of time. Maybe you are lucky and find out a good one that suddenly did a x10 and you have good money then. But a lot of them dont survive and they may be forgotten.
So i try to stay away from them. The only one that i like is Ethereum, but bitcoin is the most safe if you are gonna have money on cryptocurrencies.
if talking about money inside crypto alts are the best way to grow your btc as pairing really allow you to earn more btc but lack of knowledge will
just lead you to bankruptcy as I also love playing around trading alts but very keen to look deeper before placing my investment making it sure
that chances to earn is bigger than losing money.
