Do not expect a doubling your money every hour!
It is a normal speed when you are receiving your payments like now.
At first I made a system, when you were receiving 0.001 BTC for one day (for example) and 0.01 BTC for 10 days, and 0.1 BTC for 100 days. But after some time I decided that it is bad and nobody who invested big sums did not understand why is he receiving payments longer than others?
Some users started to divide payments into a lot of small pieces, and it is bad too. Bot made a payments when users received 0.00010000 and 0.00023412 was a Bitcoin fee.
Now, if you have a 0.001 BTC payment, you should wait as long as who made a 0.1 BTC payment and who made a 100 BTC payment.
Of course, when you are getting your 0.001 BTC doubled for 2-3 months, it's too slow.
When you are getting your 100 BTC doubled for the same time, it's ok.
If you want to know the real doubling of money in couple of months is amazing and very fast.
I do not understand why a lot of you are thinking that it is slow.
Maybe you should go in "Gambling" section and you will see a titles like: Double Your Coins in 100 hours!
But you will probable lose your money there.
Betting money with a 100 hours delay or investing it - it is absolutely different things.
