Yes dash had what is commonly referred to as a accedental instamine as opposed to some coins that have a planned instamine where lots of coins are mined in a very short period of time. These are usually pos coins and they mine all the pow coins in a few days to a few weeks or more.
Monero is a good example of a fastmine but it could be considered a instamine too, which I don't think applies but who's to say.
Look, I get that you're invested in Dash, I get that you want to defend that investment and that's allright... I do like some aspects of Dash, the governance system is nice and all... But your writings above are on the edge of delusional. An investor/enthousiast should always remain objective, you sir are not anymore and for an investor that is very dangerous...
Don't get married to your investment...
best regards,
