What a coïncidence because I had the same thoughts as you. I did invest into BT2 and can assure you made a lot of money on it. But got also very very lucky. I managed to buy a first stack in the dip. A second stack in the big upper. After that I sold everything and bought back full on a lower level. Than I tried to get some extra out of it by selling on a next upper and buying back on a dip again. Once again it went up after that and I managed to sell everything again on a higher level. My intention was to do one more trade like that but somehow I got away from trading a couple of hours..........................and that was my big LUCK
But reading haejin recommendation on that it would propably made me a miljoniare. I was in A LOT
