everyone will always try to get bitcoin and make transaction and that the key to the future of bitcoin. I hope it will always happen
In general there are many currencies that are taking care of an individual but bitcoin is the best of all as you can expect higher returns in future if price goes higher.
if you are only interested in investing and taking some money out as profit then there are many other options in real world that can do that for you, or if you don't want to go so far then just take a look at some altcoins, they can give a lot bigger return to your investment.
but bitcoin is so much more than just a return on your investment. there really are a lot of benefits in using bitcoin as a currency. and that is one of the biggest reasons that is contributing to bitcoin's growth.
