I'm in this coin too, by 1 year and six months, and didn't have any issue, price is stable, in the last month, a good rise, probably because on July the start of the masternodes, are demanding coins to reach the 10,000 coins needed. Satisfied by the return, inflation is not so big to crash prices, 25% will be there only for this year and the next, then it will be reduced to 5%.
