what is going to be the cheapest cryptocurrency to invest at present and get double future return from it?
I would choose TRON, Cardano, and Stellar. They can at least double your investment in a year. They are moving fast and show a lot of promise ROI wise.
Cardano is my top choice. Theres a big chance that this can go higher next year so be prepare for that. Dont just look for the value of a coin instead focus on their technology because no matter how much they value today if they offer a good technology for sure it will rise high.
