It is known how folding points will be exchanged into curecoins? I mean exchange rate or sth
Currently, the folding pool pays out a certain amount of Curecoins per day, right now 7488 coins. The PPD represents the points that you earned in the last 24 hours, and is used in calculating the distribution. Say, for example, that all Curecoin folders combined folded 10,000,000 Points yesterday, and you folded 100,000. You would get 1% of that day's payout, which would account for 74.88 CUR.
how many each did the 1 btc investors get?
10,000 coins - pretty steep compared to where it is right now but that investment was months and months ago so they did have significant risk. Plus there were only like 10 BTC total of investments or less. So basically 15 days worth of mining coins were given to investors.
