We cant just give our money to them. We make sure we wont lose our investment thats why few people who invest. Everyday i saw many complains that they were scammed by hyip ponzi sites. You cant blame us why we're so selective on where investments we put our money at.
I dont blame anyone. What I ask is why there s not more legit supply of good investment opportunities, to put it that way.
There are some good investment opportunities to be found on this forum, but usually not in one of these general threads like you mention in the OP.
Take Crypto-Games for example, an investor is posting his progress on a thread in the Securities section of the forum and has been doing so since February 2017.
Since then he has earned a total profit of +27.96% in BTC on his investment, turned 1 BTC into 1.279598 BTC.
