Likely because we still have no widely known mobile wallet ( monerujo could need some marketing ), no HW and people likely just hold their Moneroj on exchanges
The GUI is pretty functional, I don't think serious holders (hodlers?) are all on exchange at all.
An HW will come - it's a matter of time only, it's simply that Monero is more sophisticated than other Bitcoin 'clones' and therefore not as simple to copy/paste code into a standard HW.
Monero is superior tech, they need to catch up, not us.
Txs difference could also be about pool-payouts... afaik monero crams together as many as it can and so you got 1tx in the explorer to "x" miners .... no clue how thats done in BCH but id guess a tx each ?
