2) when the presale is over, then i will find my coins just in my wallet?
Based on the explanation from the related website, they state that investors or buyers using Solana will claim their assets through the Solana network, while buyers using Ethereum, Binance, or credit cards will claim their assets through the Ethereum or ETH network. Additionally, they state that it is a meme coin based on their site statment, which means it doesn't seem to have any clear utility. Therefore, I advise against investing too rashly, or even better to avoid it, due to the unclear vision or even hasn't the well-known backers/investors behind it. And, I recall participating in a presale program similar to this once, instead of expecting a return after the presale, I lost my assets because they disappeared.
