It's as true as that graph is. It was just the first result I got for "DASH transaction volume", because I assumed that would explain why it doesn't matter whether DASH raises the max block size. I can't find another one so that's all the info we've got.
I figured Dash would have way more transactions than that throughout the course of a day. Then again, its only real use is as a speculative instrument--no one takes it for goods & services that I know of. The darkweb (which I don't frequent) doesn't even deal with Dash to the best of my knowledge.
I'm pretty sure that Alpha Bay has wallets for Bitcoin, ETH, Monero and Zcash, but obviously the merchants accept what they like and almost all of them just accept BTC. I suspect that's the case for most other dark net markets as well. Some people do gambling with DASH because of the quick confirmations, but other than that I can mainly just think of trading to be honest.
I know there are tons of Dash haters here, but I like the coin and I just recently bought a little. Just a little, mind you. I'm hoping at $182 that it's not all downside. lol
Fair enough.
But anyway, my point is that when DASH isn't actually sent very much, it does what it likes in terms of
max block size. Bitcoin is not the same. Also, Bitcoin is a lot bigger and has a lot more active developers trying different things so consensus is harder.
