I sort of want to say "Well we weren't really taking direction from Jackson at that point" but that doesn't necessarily mean nothing happened (apologies for double negative there). FWIW I was backing merged mining in internal discussions for most of last year (coins remaining in conflict for mining power tend to end badly).
With respect to mining schedule (and I wasn't on the dev team when the decision to stick with the code as-is was made), it's very difficult to see Dogecoin having survived it's end of mining from December last year, with zero block rewards, either.
Jackson absolutely had Billy under his thumb at that point without a doubt.
I was for merge mining as well with a 0 block reward or something VERY small because the miners would mine DOGE for the publicity alone.
It doesn't cost them anything additional to merge mine DOGE.
I was the first to bring up merge mining to Jackson privately through Facebook... he gave close to no shits and I always got the vibe from him that he purposely wanted DOGE to fail to prove some strange point about cryptos being a pump n dump. (not trolling, but this is truly how I feel)
I'm absolutely sure if DOGE maintains course as is it will soon only trade DOGE/LTC. (again not trolling or fudding ect ect... check my post history in DOGE if you so wish)
Billy dive-rolled out of the project before we actually went for merged-mining in the end, Max/Langerhans was leading by then. Again, could well be Jackson was directing, though, to be honest I was mostly tied up with other stuff at the time, made my argument and mostly got on with coding.
Not a clue about Jackson - I know Billy really never expected to end up running a currency people used, I think Jackson sort of wants to, sort of doesn't want to. We're as independent from him as we can be, at this point, although he still owns the domain name, which complicates matters.
Why would DOGE/LTC become a major thing? Do you mean we'll end up primarily exchanged as people shuffle mining rewards for the coins they actually want?
