Nothing better than DCA.

25M from London, I’m solely buying crypto as investment since last 3 years and yesterday i have realised after watching swan ads on bitcoin conference and visiting their website that even if i would have DCA half the amount i have put into crypto in last 3 years i would have had a full bitcoin and i have way less than a full now. They have a very nice DCA calculator, please check guys. So all I’m gonna focus for next 4 years is do weekly purchases no matter the price. Can someone recommend a good platform? As seems swan and river don’t operate in UK.
