Nowhere was it stated the 100 confirmations was due to low hash rate. You are making that up for your own purpose.
How about PRT/BTC on CoinMarket.io?
It would be quite slow to deposit, considering a 100 confirmation requirement...
(a hint to the coin's dev: the 100 confirmation requirement is ridiculous when you have enough hashrate (eg. not a dead coin))
Or, you know, maybe that was stated somewhere..?
