So, everyone knows that there will be no more block rewards when we reach ~2140. But what do you guys think will happen after?
I personally visualise 2 possibilities:
- Bitcoin is already widely adopted, so the giant community will keep the system running and functioning. Maybe not as easily as today, but with a big enough community, the transaction fees will be high enough for miners to keep on doing their thing.
imagine we kept to a 2cent tx fee..
right now with a total 4200tx per block limit(1mb). the max tx income for solving a block is $84.00
if the block limit is raised to 20mb, the max tx income possible per block is $1680
if the block limit is raised to 32mb, the max tx income possible per block is $2688
so based on limits proposed and known about in the next decade $2688 is the top miner income, where users wont be too upset to pay a fee..
sooo. although tx fee's wont really be fully essential in the next decade. it is something to think about in the 15+ years, when there is only 1mill coins left to mine.
so lets think about the yearly income of miners solving 32mb blocks.
$2688/block=$387072/day=$141,281,280/year
at a $141million potential income stream per year.. even 3 farms spending $20mill each on equipment can still make $27mill profit each per year..
which will keep difficulty high as there is soo much equipment hashing..
or on the flip side,
1 million people spending $60.00 each, will get $141.00 in return($81 profit), each year.. which will keep the blockchain decentralised..
either way, there is still profit and incentive to keep doing it.
-Bitcoin has a small community, much like today, and starts to crumble without support of miners, and mining fees will become huge, and so the users will leave. Bitcoins will be left in the transaction pool, and the Bitcoin ecosystem will come to a halt.[/b]
Are there any possibilities I might have missed? What do you guys think?
less miners means more slices of pie for those who remain..
yea we might see 10 farms turn into 3.. but either way it will still find an equilibrium where there are a nice amount of miners who can profit..
just remember it only requires 3 miners.. (big or small) to keep an honest system.. so relax you are thinking about problems decades away, which will naturally sort itself out by changing from different strategies for mining.. and as i said there is upto $141mill potential yearly income, so thats always going to be tempting
