you can try to mine nimiq or pi currency , they will have a good demand in the coming years and these coins will surely grow in price with the passage of time same like xrp and others
my favourite is dogecoin because it has low fees and usually i withdraw from exchanges in doge coin and convert to usd to save on fees , other currencies withdrawal take at-least 1$ but for doge it's maximum 0.05$ so lots of usd saved
