The limit imposed is both advantage and disadvantage. It is hard to predict how would BTCeconomy work.
Capitalism is driven by credit and monetary policy. Economy of inflation prooved more successuful than pre-WWII deflationary economy. BTC and the 21 million limit aims to deflation.
However i can imagine BTC banks and BTC-banknotes (not physical - but simply loan-derived money as they work by now). If this happens then even cryptocurrency economy can be inflationary, but then the 21M rule is not in place.
No Sherlock money. I would most probably fail. I am not good to promote something new. I am filthy parasite that only jumps on bandwagons. I was about tu buy BTC at 2, then 5, then 30, but EXACTLY as OP says, I found it too difficult. Then I was about to buy LTC when it was for nothing and again failed. Then I wanted to mine dogecoin, but failed again. Sticking with USD. Doing well for now
. Nobody else is genius like Satoshi. But I envy the first people who made first clone-cryptocurrencies. They were quite smart and I blame myself for missing it. Now is too late with setting a new currency.
