all do bitcoin, smaller % daily interest (no double your coin BS here), daily payments...... but they return your principle to start over again, and again and again......
but remember, only invest what you can afford to lose. Nothing is safe, but in the case of these sites their plan wasn't to run with your coin in a few days like 99% of hyip ponzi scam admins that advertise their sites on this forum.
My advice is not to invest your coins in hyip sites,......
if you can make coins in other ways. I cant, I have about 60minutes free time everyday (at best) after looong work hours and a family to raise. BTC has always been a hobby, i love crypto and gave up mining yrs ago so I invest these days. This keeps my faucet topped up and profit for storage.
As for EMICoin, im at 160% and utilizing their services to the fullest.
I do wish the OP all the best.. (although im afraid his next 200btc depo might kill the site, but we'll see
)
Cool that you're at 160% already.
How much was your investment? In other words; how much did it cost emicoin to let you get to 160%?
My test deposit was just under 1btc. I never re-invested due to their high payouts and higher probability of a sooner collapse.(about this time a similar site I24-btc with exact same invest plans collapsed so I sat on my depo and withdrew daily from EMI ever since) I have been with EMI since march.
Good luck with your investment. This is truly a great test of the EMI admins mettle.
