XRB, now the price is very low and new events , wallets, exchange, brand, are comming , so now is the best time to invest on them. Dragon Chain also, it had a  dip but now is in resistance mode and soon it will go up again. Try to invest with the coins where you can see a long resistance level after a dip and the one which offers a good product , have a whitepaper and good discussion amount in the social networks.. Good luck!!
