Hello,
So if I'm to understand this correctly, difficulty is getting harder right? so what if it gets to a point where its just extremely hard to mine and supply gets so tightened that regular users are out of game altogether from mining.
It actually adjusts up AND down depending on how much mining power there is on the network. These adjustments seek to keep the supply at about 1 block discovered every 10 min. So mining may get harder, but the supply stays the same. Eventually the coins will be mined and "mining" will switch to routing transactions for profit.
Now -it can only be purchased and very limited quantity? won't that end up becoming same like fiat money? few control the interests of others?
No because fiat is centrally controlled and that leads to unfair practices. The issuers of fiat can just print as much as they want, even though that reduces the value of the fiat you have. It essentially allows the issuer to steal value. In bitcoin no one can stop you from using it, make you use it, set the value, decide who gets it, print more... All this and more can and is done in fiat systems.
Rich getting richer ? I understand the concept of sharks eating small fish and what not -I also understand that recession and progression are part of business cycle but computing isn't going ahead at a pace where we can continue to mine -so what's the path? just collect and that's it?
TIA
Consider that anyone can buy some amount of BTC and realize the growth in value. When the price rises the rich may get richer, but the poor get richer also. Whether you can afford to buy $1million in BTC or $.01 we all see the same percentage in growth.
It's just money, that's all. It is primarily a convenient store of value to trade for goods, services, etc. A fair money anyone can use but nobody can control. The opposite of fiat.
P.S. You are asking the right questions!
