I only encourage people to buy tokens at large exchanges like Huobi Global, Binance, Okex.
It is one of the reputable exchanges and will guarantee the interests of investors. Besides, I strongly oppose buying tokens on small exchanges like Coineal and IDAX, VinDAX, ... all the sold out projects in a few minutes are just fake, they fake the volume!
Stay away from exchanges like that, just focus on the big exchanges like I just mentioned. You get the security of buying tokens.
