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
Yes, I think that rather the first is that there is not enough money for investment, many have already invested everything, and the market situation has just started to recover, but this does not mean that all losses are compensated, I personally buy only 10% of my income. I prefer Ethereum, I believe in a project that will only get better, and then the price will increase
