<prompt> Human: I bought my house about 2 years ago for 365k and currently owe 265k on a 30 year mortgage. 48 years old, 3 kids none in college yet. Somehow I made enough USD on BTC over the last couple years that I have enough to pay off my mortgage. Im torn, because this bitcoin rollercoaster is a fun and existing one to ride - especially when its going up. But, I know it has the potential to crash right back down before I had a chance to cash in on some gains.Anyhow, is it solid financial advice to pay off your mortgage? My plan is to wait until I have 2x my mortgage balance in BTC and sell half my coins. Pay off my mortgage and let the the other half of my BTC ride the coaster. Paying off my mortgage is attractive because I get pissed off every time I read my mortgage statement has 50 or 900month to interest! My family income used to be about 130kyear but switched to a simpler joblife and make 90-95kyear. So, paying off this mortgage seems attractive. Principal 433.21Interest 875.24 Escrow 497.81 Fees 0.00Total 1,806.26APR is about 3I do have Roth IRAs, 401ks, and 529s all totaling about 200k. THANKS!---throwaway account---  <response>: Mortgages are the most expensive tax break anyone ever came up with. Get rid of the mortgage as soon as you can.If you are cashing in BTC make sure you keep enough out to pay the capital gains taxes.
