However, it seems the amount was actually 0.04
BTC and not 0.4
BTC as claimed in the OP.
If you look at the year when he made that post, it all makes sense actually. BTC value was around $600 back in 2016 which is why his 0.04 BTC is now worth 0.4 BTC at current rates($8500) which is why this is not a typo.
Also, based on what other posters mentioned, it looks like op has no chance at regaining his funds which is why it puzzles me as to why he decided to try again in this manner after so many years.
