You can create bitcoin replica's ad infinitum. Pointing miners to build a network takes a second.
Look how stable the BTC/LTC exchange rate is relative to BTC/USD. You can inflate the total amount of cryptos via substitution. If the price of BTC is too high people go to alts. This isn't a theory its been happening since spring 2013. Litecoin becomes very fungible with BTC.
Bitcoin is now half a decade old. Stagnant development has kept it in a permanent beta stage to give off the aurora that it is the "new" thing. The development "talent" pool has also been a total disappointment. As with all open source projects, no real incentive's in place. The biggest development in the last 12 months has been changing the name to bitcoin core.
Bitcoin userbase is as small as ever. Couple thousand unique users daily at max. All these pumpers have told us about the adoption that's coming, but somehow never materializes. We then quickly hear the excuses China, Mtgox. etc. Look how fast coinmap.org has slowed down, and most of the business's on there are shelling VNC's.
Sorry guys. The bull market was 09-13. The easy money was already made. Sure bitcoin can rise 2 3 4x from here, but another 100 bagger? Not a chance.
You can make your own physical currency as well, just smelt some copper and other cheap metals and mint it in a nice coin that does not already exists. But that doesn't mean your coin will gain any use, nor will it compete with the dollar.
Just like Altcoins will not gain traction and they will not undermine bitcoin.
Also we are right on the long term trend line. It has been stagnant for months before. It's just the calm before the storm.
Actually you CANNOT make your own physical currency, direct violation of the law in the U.S. and you will go to jail for it. Google it.
^^ Lives in US, assumes everyone else does. Your laws mean fuck all outside America, google it!
US laws are (unfortunately) enforced all over the world. Google it!
