Thanks. Check out Roy Murphy's YouTube channel (named Bitconnect channel). He shows it all to you, the owners and the open source code, in broad daylight, for anyone who cares to look. The old "I refuse to look at the evidence therefore there is no evidence" is an old tired game that only fools yourself.
So I see no difference between this and stock market daytrading. The trading will stop making a profit when Bitcoin's price stabilizes and goes flat, and that will happen when Bitcoin stops growing as a medium of transaction, which I don't expect to happen in my lifetime any more than I expect the internet to stop growing.
If you find other opportunities more appealing, that's up to you. This is one I'm comfortable with while it still makes money.
