I have seen 3 such ICOs. In one even took part. When I bought tokens at the same price, and after 2 weeks, when the sale was already open, the price of the token became less than the purchase price, and only after a month went up. I barely returned the investment.
Currently, you would not be lucky to return your funds. Now is the time to buy assets on exchanges at very low prices. Many tokens have become tens times cheaper than the original prices.
The loss of expected benefits is not as terrible as the loss of assets already invested. Good thing you managed to get your investment back.
