i think much better to buy a low price mate to get much profit when that coins go upward or when it bullish after 6months. Instead of buying today cause like you said the price is so high.  . Maybe it will fall down although  all currency is alway fluctuated . I suggest to wait what will be the result what i mean if it will continue to climb or it will collapse after 2-3 days maybe week.  Learn first the movement of coin before you buy. To gain profit.
