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.
I don't recommend any new coin because of scam issue. If you don't want to take risk & really want to make profit then try to investment any of Top30 coin/token in CMC (Coinmarketcap).
I think this is one of the best & safest idea ever
This will make you safer. The market is picking out good, potential and reputable coins to exist in the market. Coin trash will be discarded when it has no value. Investing in coins on top of CMC because they always have plans and new projects to develop and create credibility for investors.
