You wrote all of that just to say those words, didn't you?

You say you want a good return but then you say BCH is currently the best...how are those two related? and if you actually believe that BTC is the past, then you clearly have no idea what you're talking about and most likely you will lose all your money.
But i will give you some advices: BTC price is going down so this is the perfect time to buy cheap, keep your altcoins for the time being, and if you can buy more, do it, i would recommend XMR, Dash, and NEO.
If you still believe in BCH, well, i wouldn't recommend to buy right now since the price has gone up a lot today.
