I don't think the price is tied to the difficulty. hmm I may be wrong though I'm totally new. Anyway I wanna ask what are my options to sell/ BTCs ?
The price is tied to difficulty and overall network hashrate.
If network hashrate increases more than difficulty then price will go down.
In which case the price for 1 BTC will be alot higher the day difficulty gets so high that mining is no longer profitable.
I'm not 100% sure if I've gotten the system right though. Can someone prove me wrong?
