Oh yeah, so far as they are not ready to learn and they are also not willing to work hard towards making their own money this is exactly what is going to happen. Growing up in this industry i have also fallen a victim to these scams but i learnt my lessons and have been good all this while.
Why would you offer 0.1BTC to someone who claims he can give you 3BTC lol
now many are like that and many more HYIPs circulating within 24 hours can get a profit of 500% that's just a hoax because at the moment there are a lot of new traders who don't have much experience being fooled by HYIPs and project scams, there must be information for new traders so avoid cases like that.
Indeed, we will always be easily tricked by investments like that, especially now for HYIP with more and more bitcoin payments and making profits up to hundreds of percent in just 1 day, we really need to pay attention not to be easily fooled because it is not easy to be able to double money up to hundreds of percent in only a short time.
