Hello, I'm new in the "crypto world" and I'd like to know if it worth invest in allcoinhodler
No. It is neither worth it nor safe. If you send them your money, you will never see it again.
Take this as a rule of thumb for spending money in crypto - if it sounds too good to be true, it probably is. Any service which promises ridiculous returns on investment, such as doubling your money in x number of days, is always going to be a scam or a Ponzi. If someone really could double your money, why would they not just double their own money over and over again and make themselves a millionaire?
If you want my advice on the simplest way to make some profit in crypto - buy bitcoin and be patient.
