Shitcoins will not make your billionaire, because shitcoins are the dead coins that havo no the real value compared to the alternative altcoins. Instead of holding shitcoins l prefer hold other potential altcoins. It can be ETH, XRP, Zcash, and BNB. There are more chances for them than shitcoins due to the huge buying intention after the confirmed rumours by the market participants.
