What do you guys recommend me to invest in?

My last bet was pretty spot on with bitcoin, so here's what I suggest doing.

Wait for bitcoin to drop, its been happening a lot lately so it's creating some opportunity, throw in at least $100 - by the next week bitcoin will most likely already gone back and stabilized at the previous point, at this point sell, this last drop you would have made at least $100 from doing that, (again assuming you only put in $100)

Now if you WANT to go long term, simply leave it invested till it goes higher, right now though BTC is having problems so I think you'll have more luck with that method ^
