Transactions are too slow. Will someone fix it or do we need a better coin?
Yes, the time it takes for the network to confirm securely that the transfer took place takes a lot, compared to other forms of money transfer, such as credit card.
However, the trust that the Bitcoin Blockchain conveys is a very positive point, not to mention that the fees charged by Blockchain to effect the transaction do not compare those charged by credit card companies.
If you are looking for fast transactions, but which are still in beta, there are Altcoins that focus on speed of transactions, such as Vcash (XVC), which has the zerotime technology.
Not sure about street transaction but very confident about all your plastic and online transactions. They are actually quicker than you think; 1 confirmation can use at most 15minutes for its be processed and it all depends on the block size. Otherwise be patient, you assured your transaction will happen anyway.
