What altcoin is the best for short-term speculation, some of my friends offline have speculated people but then I don't have much faith in meme coins.
If i may go by in giving you my recommendation here, you can choose ethereum, doge, litecoin, these are the three altcoins i know has a better future prospect on investment if you can hodl, there are a number of digital altcoins recently introduced as well but i cannot take the risk in those currencies for an investment because we don't know what may come after their speedy performance within a little time unlike those that have been consistent despite market challenges.
