There's also a scam I found, in just 4 days, your invested bitcoin will gain 100%. A lot of my fellow countrymen invested on this site, most of them are newbie in crypto, they don't even know how crypto works. They just invested on this HYIP, because of 4Days increase of 100%, they said that in the first 4 days they invested with small amount, the site succeed to give back their 100% profits but they re-invest, after that BOOM.
Please be careful, the site is now offline
They also use telegram bot(@bitxBot), which the sending of bitcoin and creating your account is done on the telegram.
