I advise you to look at the currently undervalued altcoins that cost less than $1-Verge, Cardano, TRON, Stellar. But, the most interesting and promising for investment coin for today I believe Ripple.
Ripple is a centralized and regulated cryptocurrency created specifically for financial institutions
XRP is what banks will be interested in....NOT Ripple. They will use this technology with their own currency and get rid of Ripple.
Ripple is made for banks instead of sending SWIFT, they will use Ripple.
