Hhahahahha, good luck searching on that one @intelliguy !
It is Swiss-german, which is a bit in between of a dialect and an offical language! Very difficult to find online and spoken and written different in every region (AKA challenging)

But uhhh, crypto meetups? Hell yeah I would go if possible, in fact I will be attending Steemfest in Poland this year
Proficiency in all languages? Dutch fluent 100%, English fluent 100%, German 70% and Swissgerman is the most fresh to me, so I would say 30%
