I do not get you. Tell me
Today begins the sale of coins AE on its own blockchain
1ETH = 1100 AE
It is almost four times cheaper than the coin is now traded on the stock exchange.
How so?
What are you talking about? As far as I know, there are no sale going on and the only place you can buy AE is on exchanges or OTC trades.
Maybe mistakenly you went to a scam website?
It seems this guy clicked on scam link some people still sending that kind of promos to buy this coin at cheap price to make other greedy and let their money. Agreed with you it is better to buy from listed exchange or from a trusted person.
