While bitcoin will grow in value relatively quickly, there is no point in using it as a means of payment. Why buy goods or services for bitcoin, if its holder knows that after a while its price will rise and he will be able to buy even more goods for the same amount in bitcoins?
Therefore, the initial plans of Satoshi Nakamoto to use bitcoin mainly as an alternative means of payment can be considered to have successfully failed.
It is too soon to make that conclusion, if bitcoin really becomes as valuable a we think then bitcoin is not going to be used for your everyday transactions but for really big ones, I know this is not what most people want but that could be the path that bitcoin could take, what we need to figure out is which coin will be the one that will be used for our everyday transactions, litecoin does not seem like a good option and ethereum has the same problem of bitcoin with the fees, so the door is still open for a coin to take that spot in the case bitcoin is unable to fulfil that role.
