in this day the price is so high then it is not the time to buy bitcoin wait for the price to go down like 200$ and then buy 1 btc and wait for the price to go up 
like 400$ then you wil win the double but if you buy it now and the price go down you will lose money
like 400$ then you wil win the double but if you buy it now and the price go down you will lose money the new bottom is 350, you will see, because it will accomodate the halving, there is no more sub 300, the last chance was before this pump
buyers had plenty of time to accumulate, 10+ months, you had to buy cheap bitcoin, now it's over
if you think that 200 value could last forever, it would be a fun joke i would say...
