Well hello there,

i'm new to Cryptos but not new to investing.

blablablablabla

And I will repeat what others said before me. Blockchain technology is revolutionary but BTC is not - It is not more than a speculative asset.
Anybody who "believes" in BTC as a decentralized currency is doomed to fail. It is the king now, but there are no kings, only princes.
So, as you do not know the intrinsic value of a BTC you might end with a bunch of worthless private keys.

Anyway I'm surely investing down on teh road for the fun of it.

BTCs market cap is laughable. Nobodys gonna "attack"  
The only conspiracy theory which could apply is, that BTC as an implemention of the blockchain technology is a crucial social experiment  

Two facts from my side:
Every larger company is currently trying to reduce the cost associated with hard cash.
This is the "digitalizing aspect" everybody is talking about. Yes (slow) companies will arrive in the 21. century too.
Finance institutes are looking for experts in blockchain technology (some job offerings I recently read). So count 1+1 together...

Amazon will not stay there forever. Remember IBM and McDonalds?
Sure BTC got under developement, but in my opinion its inherent technological design is broken, if you want it to use as an actual currency.
And that's the argument of many "believers". Current attemps in improving scalability comes at the cost of loosing security, let alone the sheer amount of electricity needed for buying a coffee.
