I second the buy a fixed USD per two weeks / month. I kick myself for a lot of btc miscalculation (love my 20ish btc t-shirt) but that one has at least left me with a sizable (but less than 10x) return on average if I liquidated right now, rather than nothing if I just stayed away. I also figured the price would improve after the halving day last year since the supply of new bitcoin would go down, it did, so since I think bitcoin can last at least until 2020 (next halving) as the biggest cryptocurrency I figure buying more now is fine too. What other easy-to-buy asset offers the same chance at 2x+ over 3 years? I still put most spare income into an index fund with the conservative 5%/yr target that lets you retire when 4% meets cost of living, but if bitcoin keeps growing I'll soon have more in that...
