So in conclusion: Bitcoin is the blanket cover for what cryptcucrency and digital currency stand for and only those that hold Bitcoin should be seen as the smart people, not those holding and gambling with shitcoins.
Bitcoin is to be seen as the mother coin of all cryptocurrency. So this i can agree with you.
People are trying to adept to the concept hence making their own tokens. and with that they are creating all kind of shitcoins as you mentioned.
for me though, i always try to keep all my holdings in BTC, others will fade away eventually.
