Best investment is to buy Bitcoin and hold it or use the bought Bitcoins to invest in a casino bankroll. For me this is the best investment, but maybe there is an ocult investment only few people know and are earning a lot of money from it and won't tell others about the method. There is always something like this happening, if many people know about the method, the method becomes worthless for all.
Casino bank roll is not good in my mid, Just with a little amount and we can't get a decent profit from there. I think vslice has offered best dividends for the investors rather than casino bank roll.
Bitcoin alredy being best investment for us, just hold them and try to wait until the price goes higher than before. With lower risk and it's really good investment in my mind.
