I think the only two things that i hate about bitcoins are slow confirmation and the price of bitcoin that is continue rising because i can't afford bitcoin now because it's too expensive for me lol.
Do not worry too much. If the confirmation time to too slow, there will be not much usage of bitcoin, the price will not rise too high.
Lol seems you do not need to fear it bitcoin has fluctuations so it is unlikely prices will always go up dude. there are times when the price of bitcoin will go down it is an exact science. so do not be afraid bitcoin prices will always go up? it is impossible? IMO
but for the time wait for confirmation I can not solve the problem
The volatility of the bitcoin is too high. If the volatility is less than 5% in a month, more people will use it.
