It will not be difficult to create a super simple laser miner.
Have a few setups and do a trial run on bicoin-cache.
ok. suppose someone can turn on 49% of the network now using a different algorithm to calculate and search for when the recalculation of complexity will happen? in 1 week) and this already gives reason to worry)
i don't care what will happen there. yesterday it was shells, then gold, then fiat, then bitcoins, then another currency))) it has nothing to do with life itself.
