Maybe there are several reasons people have not to buy ethereum, most of them are not having enough capital to buy this ethereum and there are several other reasons such as they are afraid that ethereum prices will decline in the future and they are afraid of future losses
Another reason is, there is a group of people who think that ethereum is a scam, even though it was he, who ransacked the crypto world since the appearance of his token. If someone is think positive about it, negative thoughts will not disappear. Because a person's personal response is different.
