i always try HYIP but only if that site is new and just once with some bitcoin but actually its not much, so far i've got double from them i.e bitcoinsdouble,com after that i leave it, i would never to deposit again because i think i will lose all of my bitcoin if i deposit again, but iam not sure if we're going to get double at the first time
Same here. Early investors always get profit from those HYIP. IF you are a late investor please think trice if you will join that HYIP or much better not to join it anymore even they are rocking for a weeks.
NOT always. HyIPs are somewhat like waves, i think. Sometimes they run fine for a while, paying small amounts, then start to not pay bigger amounts, then stop all withdraws.
But at times it seems there is no one investing besides those who think they can be fast. Then they invest and because nothing more comes in, the owner stops withdraws instantly. It looks then like no hyip is working at all.
Guess most need to learn from their own failure.
And sometimes you just deposit and the deposit never reaches your account. This happened to me two days ago. I sended 200k satoshis (always a small amount first just to try) and the deposit never appeared. Contacted support, but it did not reply.
It is really risky.
