My biggest problems with Bitcoins is if fluctuation of the price comes.
and then sometimes my transaction is extremely delayed before my confirmation
comes in into my email

Right but at the same time we also have to understand that there are fellow bitcoiners who earn a lot of profit with just this. I love how the price fluctuates and gives us opportunity to earn with it.
Exactly someone takes price fluctuations as a threat and some view it as an opportunity to make quick profits, and people will really hate if price remains stable for a long time.
Yes undoubtedly bitcoin have a problem of price fluctuation. But sometimes its more excited when the price of bitcoin increases. But i dont think bitcoin has more bigger issue than this.
I guess the price fluctuations are the main attraction bitcoin so as to attract investors see bitcoin as a profitable investment.
i really think that it is true, price fluctuations allow you to make a lot of money in my opinion and this attracts a lot of people to bitcoins right now i think what is really great
my biggest problem with bitcoins is the fact that the confirmations take a really long time to confirm in my opinion, because of that i sometimes have to wait until my deposit counts
Confirmation is sometimes impaired probably is a problem that we all experience and I too have experienced. Maybe it was a reasonable stay if corrected would have been very much better. I never experienced a problem with the transmission up to 4 days and it was very boring.
