Ruble need a couple of years to loose it majority of his value against dollar but have you checked the BTC price it can go upto 1000+ and can come back to 100 within a couple of months.
The market capitalization of bitcoin is still too small. It is still early stage of bitcoin. When bitcoin reaches the market capitalization of 1000 bn, the value will be very stable.
It will be stable even at 100 billion, or when more people will use it. Right now the big players are manipulating the market, once the distributioni s more even, it will have less volatility.
Distribution will never be more even because big time whales will not allow that. Market manipulation will never end.
Eventually even their supplies will run dry if they don't have any source of income.
It might take years, decades or centuries, but if they don't contribute anything in exchange for bitcoin, they will eventually run out of Bitcoin.
Or they get richer.
Look I dont care who hold bitcoin, it can be a 70 year old grandmother that discovered mining in 2009, or a wealthy wallstreet-er who invested in 2012.
The point is that no matter who owns it, the mere matter that they own it, makes them superior in financial circles. All the other dumb people will hold bonds and stocks and their money will be gone. The bitcoin wont be.
how do they get richer?
if you're just spending bitcoin, not producing anything, nto mining anything, how do you gain more bitcoins? Especially if you already hold a majority of bitcoins?
The rich get richer in fiat just because they are the only ones who can lend money they don't even have, and than charge interest on it. That's why they are so unbelievably rich.
With bitcoin, this scam isn't possible.
