I actually think that having 80 times the coin supply of BTC is one of the reasons NXT will succeed.
Bitcoin is effectively in competition with gold as a non-fiat store of value. The price of gold defines the upper limit of what Bitcoin can hit, and that's currently around $1200 per coin/ounce. Bitcoin won't go above that price because if people have $1200, they would rather trade it for a one ounce gold coin they can hold in their hand and not a computer file.
+1200. I've been keeping this same thought to myself, but since you broadcast it here, I applaud you. The price of gold is probably the limiting factor for all cryptos, and it's purely for psychological reasons. Past a certain point, it's crazy to have such a valuable unit of account be vulnerable to data corruption, loss or theft. As we've seen, when Bitcoin hit $1200, it didn't rise above it for long. Amagi Metals and Coinabul, who accept BTC for precious metals, provide the conduit for 'difficult to trace' gold. That's not to say BTC will never get over the price of an ounce of gold. BTC is much easier to move, especially across borders, than physical gold. That feature could fetch a premium. But, we will have to exhaust the demand of BTC holders that want gold before it can move significantly above $1200.
IMO, all of the cryptos that have had successful launches are 'money good'. So long as they are tradeable on exchanges, they are fungible.
