If you've a large discretionary income present, it's fine to lump sum since the funds are available. Personally, I wouldn't lump sum with everything at once. I'll like to divide the money into 3 parts, lump sum with the first part, use the second part to increase my aggressiveness in DCA and keep the last part for buying my target dip.
So I did lump sum some time back, but personally I feel now (hindsight?) that splitting the same amount into a DCA would have been a more effective approach.
I bought in Nov '24, as a lumpsum. Then in Jan/Feb I was happy but in Feb we got a bit of a dip - right up until April.
Conversely if I'd done a small amount in Nov, then bought DCA below my last buy price I think I'd have made a bundle more.
I understand and share your experience, at sometime during my journey of starting my investment, I approached the market through buying lump sum when I had some money saved somewhere I had to use all buying through lump sum, and within a month there was a dip, and I was literally panicking, and I was actually feeling I could have approached the market through DCA by splitting the money, I felt like it could’ve been more an effective approach, because I know the volatility nature of Bitcoin, it will alway recover.
But I had to consider buying through the DCA on a weekly basis when I have my discretionary income, but I still didn’t stop buying through lump sum when I have more money with me, because I also felt like I wanted to front load my bitcoin portfolio and I was also getting aggressive and I was also trying to be careful.
