a lot of coin very good to be invested, XRP has the great to thrive in the future. I think you just need patience in investing, don't sell panic your coin
I do not think like you, can see that the price of altcoin in the day today has not kept up the momentum and are falling very fast and fast, this shows that signs are bolting altcoin of investors. I think this will be a long term reduction of altcoin so I think you should not invest in altcoin at this time but invest in bitcoin. The price of bitcoin in my analysis will probably continue to rise to $ 8200.
I am agree with you I do not think that it is so easy to choose the best altcoin for investment, I think that in current time bitcoin is the best place for your investment which is comparatively less risky and having more chances to give you a very good profit.
