Last year January, you could still get a bitcoin for as low as 38k  but  as at october of same year , you could only get it almost double of that price, as at today it's now x4.
Over time, it’s increasing and not getting cheaper but even as at now we could still say it’s  cheap  compare to what future purchase value might hold..
If you're  accumulating do it with consistency while maintaining  other important resources to sustain it aswell..
