None of that explains why "never sell" is the only strategy.
And
pick one?
right, i'm saying it's a speculative investment at best (really i think it's just a giant pyramid scheme). cryptocurrencies are not actually good at being currencies, because they don't hold steady values.
and the reason to "never sell" is because the value of bitcoin is essentially
only going to grow, IMO, until it falls of a cliff. HARD.
1) finite coin supply
2) constant or decreasing coin release rate coupled with exponential network growth
2) progressively increasing difficulty of mining
to be useful as a currency, the number of coins in circulation needs to be modifiable, and coin release rate needs to be matched to the network size so the difficulty of mining coins ("value") is held essentially constant.
otherwise, the resources used to mine coins ("value") is going to increasing, making each new coin increasingly more valuable than the last, and not particularly useful as a currency.
why would i pay for something in 1 BTC today if it's almost mathematically guaranteed that in the future, that same 1 BTC will be more valuable because the amount of resources to mine any single BTC is dramatically greater? and why would i lend you 1 BTC today, only to be paid back in 0.1 BTC (or some arbitrary value less than 1) in the future for the same reason?
