most of my savings right now are in bitcoin, which i hope will set me for good in like 15~20 years of holding.
so yeah, it's kinda stressful for me as well, because there is always that thought in the back of my mind, if bitcoin crashes and never recovers for whatever reason, i may not end up in as good of a spot as i want to in the future.
I look at bitcoin as my early retirement fund. Obviously, none of us want nor expect a significant crash and loss of value from which Bitcoin will never recover. As the saying goes, bitcoin doesn't have a top because fiat doesn't have a bottom. A major threat that the ecosystem will have to deal with sooner or later is that of quantum computing. If the network takes too long to decide which quantum-resistant algorithm to upgrade to and we get people pulling different strings, that would really be bad. A split in the community due to a hard fork would be even worse.
