Bitcoin cannot be a "store of value." It is not digital gold. That would be Ethereum or Dash.
LOL, dream on.
Bitcoin is only driven by investors since it isn't useful as a currency.
the two altcoins you are clearly bag holding are even worse. look at what cryptokitties is doing to ethereum
When sell pressure becomes greater than buy pressure, the price will fall with no demand to catch it.
and Dash and Ethereum have this demand to catch it?
This could lead to a panic and an epic crash.
sometimes crashes are necessary in a market to right a wrong. and this rise to $19000 was horribly wrong and needs to be "corrected". if it corrects with a panic, then so be it. it won't be the first time a panic sell happens and will certainly not be the last.
The only people who can fix this are the miners.
If they speed up the transaction and lower fees, it will become a currency. Then when investors sell, currency use will create a demand floor to prevent a crash.
unfortunately you do not understand how bitcoin works.
miners have no power over fees or speed of the transactions. it is controlled by the block size and it needs to be limited. we can not have 1 GB blocks or we will see a doomed faith similar to what ETH is experiencing these days.
