If quantum actually breaks encryption in 5–10 years, what happens to crypto?

I went down a random rabbit hole about this “years to quantum / y2q” thing. basically once quantum computers get good enough, today’s encryption (rsa, ecc, etc.) could be breakable. not saying it’s happening tomorrow, but the part that freaked me out was this “harvest now, decrypt later” idea, where data is already being collected today and cracked in the future. And now im thinking… does bitcoin / crypto actually adapt in time? or is this just another tech panic like we’ve seen a hundred times before? i mostly just buy/hold small amounts (binance + coinswitch + a bit on-chain), not some maxi take here. wdyt??
