there are two effects with different impacts:
1) the overall deflation of all assets which can also impact BTC as you suggested above
2) bitcoins infancy with still huge potential. just imagine every citizen of the world would have 0.001 BTC...
Yea, ok. bitcoin has lots of potential, agree. but why on earth would you buy pre-crash? rising interest rates = mad dash towards dollars. everything else tanks.
imho: save your dollars and buy tons more bitcoins post-burst. then sit around and wait for inevitable wave of inflation.
bottom line, stupid to buy and hold right now if you KNOW a bond collapse is coming. be patient. noobs
