At first I really see Bitcoin as a digital currency for buying and selling goods and services online but nowadays the way I think about it changes also because it is indeed more of a property just like Gold right now more than a money because the price increase is so fast that spending it like a normal money will make you regret later on.
There are so many new players that only bought Bitcoin in expecting to earn out of it and I am not against it though but they are just riding the train with no idea at all to what it's all about. Using different cryptocurrencies aside from Bitcoin is more convenient without a doubt because the Bitcoin network is congested this fast few months and it must be improve or else there will be another coin that may become worthy than Bitcoin.
