Though I don't do HYIP schemes because in 2013 I lose heavily in hyip and since then I stop investing in hyip. But I learned from an article that said almost the something you are saying. The writer said " never investment more than one time in hyip and don't investment in hyip that has long time returned on investment like one month and above".
The writer should have said to stay away from HYIPS or should I say, Any Ponzi schemes regardless of its context. There are many investments that is
much less risky and realistic so why not search for it first to know all of your options. We can easily know if an Investment is a ponzi if it says too good
to be true things like a high returns in a short amount of time.
When we are not being greedy, I believe we can stay safer without getting scammed.
Only due to greedy, people are looking for high yielding investment opportunities and finally getting scammed.
You should know to be a bitcoin investor to prevent scam you should know it's policy, rules and regulations, proper procedure so you can easily identify if you are dealing a right person or a scammer you should also have limitations when dealing transactions and be sure that you know how to secure your investment .
Personally I would say even knowing all these things, only with luck factor we could come back with profits from any investments and not getting scammed too. Because any investment scheme may go scam after some time like after we make investments with them.
