So here I have a friend who's inviting me here on the said gambling investment. It's just simple, you'll send your bitcoin (investment on any amount) on that person then he's going to play using the money collected. After 7 days, your investment will be doubled and the money will be sent back to you after deducting the trans fee. There is a chance of losing but if your money loses, you'll. Be given a 10% refund.
Someone already tried this? Safe or not??
All types of gambling is not safe. I suggest, if you really want to try gambling investment, try to come with your friend beforehand and study how their gambling works, what type of gambling will occur. See if you think that it's an easy money for your supposed friend, if it is and if he really is your friend that you can trust with all your heart then go for it. But if not, you better prepare yourself, congratulations you got yourself a fake friend.
