I see your future........broke.
You use the word 'invest', so I assume you don't mean gamble.
There is nothing legitimate anywhere on this forum, let alone in the trashcan here, that will ROI in 8 weeks and be sustainable.
Take your 150 bucks into the real world, do a bit of buying/selling stuff that interests you, anything but give it to the liars and scammers on here.
I suggest to invest them on a bitcoin doubler site which are recently paying their users. You can find some on this forum like btcdoublex.com or btc.surf etc.
based on experience who invest first will be got profit and the late just got nothing...just carefull in invest money..
do some research will be good
becarefull if you want to invest on bitcoin doubler site,,
because you dont know when they're scammed you,, im prefer if you invest particulary like 50/50 in trading and anything
