Bitcoin or the cryptocurrency (altcoins - LTC, ETH, etc) as a whole - hindi na ito mawawala. Pareho lang yan ng internet, since decentralized ang both internet and crypto currency - this will go on for a very, very long time. Hindi pa nararating ng cryptocurrency ang "mass adoption".

Pag narating na ng crypto currency ang mass adoption stage, forever na ito or hanggang mag-evolve to a new form.
IMO, ang pinaka-malaking effect, not just by bitcoin, is the decentralization ng money. Imagine, for the first time in the history of money, you can actually create your own money using a computer or any hardware that you own. Not governed by any central bank, owned by you and valued by the community. You can also send money to anywhere in the world without passing thru any bank (unless you need to convert crypto to fiat).
Ang pinaka malaking foundation ng all crypto is the blockchain technology.
