I think BTC has a bright future. It's not just another bubble, it's a real payment system that can solve many economic problems.
bitcoin is only going to grow bigger and bigger as time passes by and we can already see this if we compare bitcoin and its uses against the very past.
for example a couple pf years ago the blocks were barely half full and now they are filled with transactions and this shows that bitcoin network is handling a lot of transactions each day and that shows a lot mroe users.
