long term holders: how do you treat bitcoin and/or ethereum?

and by that, i mean, do you treat buying bitcoin/ethereum as a savings account alternative? by keeping nothing in your savings and retirement plans and going all-in on one or both of them?

or do you treat btc/eth as an additon to your 401k and Roth IRA? while still keeping a traditional savings account.

personally, i do the latter. every paycheck, 12% automatically goes to 401k and Roth: 60% of that amount into 401k and the remaining 40% into Roth. then whatever my net pay is, 10% of that goes to bitcoin and eth: 70% of that amount goes to bitcoin and the remaining 30% goes to eth. after bills, whatever is left goes to savings. and like 401k and Roth, i wont dare touch btc/eth until retirement.

for the guys who are going all-in: do you really believe bitcoin/eth will outpace the growth of the traditional stuff? serious question and not belittling at all. just want to see some different perspectives.
