Actually I'm looking for gambling sites with minimum loss. Here is few sites I've tried till today.
Bustabit - Total loss of $60
Primedice - Lost $10
Sathoshimines - Profit $4 (This site is getting harder day by day)
unknown - profit $15 (Invested very little site pays in mbtc site like this I'm looking for)
If you have any real poker game then recommend me I'll try it. Similar sites like taxas holdem poker.
It seems that you are deeply confused about how gambling works. You won't find a better site with higher chances of winning.
As for investment options - they can change too, it is not guarantee that you will gain profit when some whale will show up and win big.
