at this time I prefer USDT as the best altcoin and suitable for investment, because the price of the coin can be classified as a stable coin and far from the risk of losing money, but if you want to choose a coin under $ 1 then the right choice is doge, the explanation same as I said before.
What the heck? USDT is a stable coin and it can't be considered as a stable coin and it's more like a fiat that already converted into the cryptocurrency. Almost all of coin on top 100 CMC are worth to invest.
The only advantage of doge is on its cheap txfees that can be used by any party to send any amount with cheap fees. Im not seeing another advantage from doge. It looks like better to invest in top 25 CMC.
