If Btc will continue to rise in 2021, there is a huge chance that it will at least reach 0.7$, 1$ seems like a prediction in late 2021.

Should I hold some xrp or should I wait for a signal that btc may go down?

I was invited to the community because I had people who were scouting for new coins in the market. I got to say, out of all the coins/platforms that I have worked with, this is pretty legitimate. They have the potential to rise in the market and their platform is really easy to use. The P2P betting system really is a good addition to their betting site and overall, the community is very nice and helpful.
