Not just shiba, but there's a dozen different others I think.
I tried a couple of them, just to see how they behave in this bear market.
To my surprise one of them was 20% in profit last time I checked ( after about a month ) the other one $50 in profit after one day. Not bad !

But to be honest I don't think I would put any money on Doge or Shiba... they're already far too high in the rankings.. way... way higher than they deserve. The best gains are made when your meme coin is ranked #800 or somewhere around there
Just consider yourself lucky. Any meme coins ranked 800 or below are most likely just scams and you will lose all your money. Just because 2 that you picked went up (in the short term) doesn't mean this is the smartest strategy. If you gamble with too many of them you eventually lose your whole stack.
