Talking about "extreme" speed, not all the time bitcoin will give you an extreme speed in transactions. Because it's one of the issue right now, many are experiencing problem with this matter. But for me, people should use bitcoin right now because the chance making them rich in the future will be gone if they aren't going to get into it.
Yeah everyone is facing an big issue with the delay in confirmation time and even the transaction fees have become very high and not all will like that but apart from that there are many best features attached with bitcoin and that attracts people to use bitcoins.
Yes we need to set aside it, because there are more good things about bitcoin and we don't need to focus with it. That is just showing that because of the delay, many people now are starting to use bitcoins and despite of those problems, many are sticking into it. Another thing, instead of the price to drop because of those problems, it keeps on increasing.
That's the only issue that bitcoin have,other than that its fantastic, We cant really have all at once,that's why there's always a room for improvement,like what they say due to its demand ,bitcoin having hard time to do transactions faster ,but it still does it job in transferring and making our transaction possible so lets focus more on how beneficial it is to us and instead think on how to developed and improve knowing that were all benefiting from it.
