Many true Bitcoin enthusiasts actually prefer to use Bitcoin as a medium of exchange. They arent interested in investment or speculation or trying to sell at a profit.
Instead, they see Bitcoin as a way to engage in free association of trade without the need for governments to regulate the exchange. With Bitcoin, its possible to pay for goods and services instantly by transferring the digital money straight from your wallet to someone elses digital wallet.
Well yeah you can transfer it quickly but the confirmation and the network being not up to par is what is causing problems at the moment. Whenever lightning network gets instituted into bitcoin then you will have quick transactions will next to no fees and that is when bitcoin will be viable for everyday use. I look forward to the day where I can live only off bitcoin and have more or less let fiat money go for the rest of my life.
