I had an initial investment of 250 on Shib and now it's over 800. Should I sell and buy some other alt-coin or should I hold? Also what altcoin should I buy? Sorry for the stupid newbie post I'm just not optimistic about Shib since it's a poop coin haha.
You don't know what to buy and what to do, this is the hardest part when you have no idea what you must do. Because some will just shill you out unknown altcoins because you are intended to do that. So, if you happen to have no idea what they're telling you, DYOR at all times.
If you are in profit and you are satisfied with it now, sell. But if you think that there's going to be a bigger value of it during the altcoin season or once the halving is done, sell.
