I think you should work hard for few more months and save more money when your amount of money reach to at least 1000$ I think it's enough to invest in Bitcoin or any kind of investment you wanna invest in. But with 200$ only I think it's not enough to invest in anything related to cryptocurrency.
It is really incredible to see how things can change, 200 dollars was not that bad one year ago when bitcoin was worth 1000 you could buy 0.2BTC now those 200 buy a lot less, this was to be expected but at the same time the speed at which everything happened was incredible and this is what has caused any people that thought they had a chance to invest in bitcoin to lament by the fact they did not took the opportunity to invest in bitcoin when they could.
