Re: [ANN] Grin | PoW Mining | Electronic transactions for all. Community driven.
I just wanted to comment here just in case that in a decade from know I can point somebody these quotes saying " I told you that the majority of cash like transaction on the planet will be done in GRIN" 
I wonder if that will ever come to reality. How are they going to beat bitcoin or eth or ripple in the first place?
Because Grin can be added as a side chain to bitcoin? Therefore integrated within it. It also provides a different function to those coins, i.e privacy as well as greater scalibility. The main rivals in the privacy sphere are Zcash and Monero. I'm not sure what benefits ZCash and Monero can provide over Grin.
Dash was a main competitor as well, but seems to have disappeared from attention for some reason in more recent times.
