I think there is nothing wrong with the OP asking this because rank doesn't guarantee someone has a strong analysis..
Do you still think the OP is sincerely seeking the opinion of other members with its question?
Thanks for your comment. I want to known have some coin that price Increase or decrease regularly? Also i want some coin that can be increase after some time.
Every day btc price increase or decrease. If you want to trade your btc keep it some exchange for buying and selling. Btc price can be change in a day 10℅. So it is risky for you.
Today xrp pump 107x. I think xrp is best for invest 2020. Other you only buy btc if you don't interest to trade.
Besides, I have nothing positive to say about a member who hasn't earned even a single merit since the implementation of the merit system. Just another signature spammer as far as I am concerned.
