i am interested to know what your opinions are about the hottest coins of 2019, what do you think is a good sound investment and why? (please state your reason) and if it's not too much trouble please let me know where i can buy the coins that you suggest.
My Vote after BTC is for Ethereum, as its still most undervalued altcoin in the market. NEO (the Chinese ethereum) is also a good option for investment.
P.S I highly recommend to DYOR before investing in any coin. Dont follow what others suggest, as no one will share your loss.
