My favorite altcoin is BNB Ethereum XRP.  Because these coins are risk free and these coins have high utility and these coins have been in the market for a long time.  Although Altcoins are risky but these coins are completely safe.  I am saying from my experience that I have made a lot of profit by investing on these coins.  If we analyze the market we can see that Ethereum and BNB network token are very good. Also most investors prefer Ethereum after Bitcoin.
