Do you know the main reason because eMule died after the arrival of BitTorrent?

[HostFat]

The main reason were the "chunks".

eMule divides the files in chunks, 9,728,000 bytes (9500 KiB).

The peer is able to share a peace of file only after it has downloaded an entire chunk, not before.

At the time the download bandwidth was obviously lower then now.

So, there were long times before a chunk was completely downloaded and able to be shared, and so files needed a lot of time to be completely shared.

There were times where a lot of peers where only downloading and not upload, because they weren't able to. (no complete chunk, no able to upload)

Then arrived BitTorrent, and the smaller part was 16KB, do you know what does this mean?

It means that peers will be able to start uploading even after have downloaded just 16KB! Few seconds.

Files were more liquid.

Money is by definition the more resellable commodity on the market.

So, what does it mean that "a money" needs more then 10 minutes to be resellable? And more then 20 minutes? More than 1 hour? ...

It means that it is less liquid. There will be less exchange between people.

There are many functions that make more or less liquid a cryptocurrency, all of them need to be considered.
