2018 might be a good year for some of the major altcoins, but I have my doubts about the performance of Bitcoin. Two of the major things Bitcoin needs to address is transaction speeds and fees. I have read articles about many businesses that have stopped accepting Bitcoin because of how volitile the price is on a minute-by-minute basis. It makes sense to me too. There is always a risk that by the time a transaction for a product has been made and the Bitcoin subsequently traded for dollars that the value has gone down and the merchant ends up losing money. I think now more than ever what Bitcoin needs is stability in its "value". I feel bad for the poor bastards who invested their life savings in Bitcoin when it surged to $20k just to have it shed over half its value in a matter of days. That may not be much to cry about for the Winklevoss twins, but for the common hard working man or woman, that must have really hurt.
