Even if you do not understand the technical aspect of blockchain or cryptography one economical principle can prove why Bitcoin (BTC) will survive and all else is subject to fail or remain in the shadow of BTC.
Scarcity! That is right. There will only ever be 21 million Bitcoin. No other crypto can say this. Take into account that Bitcoin is truly decentralized, has the most proven security, all else falls short. If you understand this, you feel safest storing your value in BTC.
Speculation is a powefull thing and I feel most people who support other projects (Like Ethereum) will eventually jump ship when the new "hot" ICO or crypto buzz train comes around. Like EOS.
Crypto's i think that will survive or wont ever hit 0 are crypto's like Monero, Litecoin or Nexus.
From here on out i will only speculate with Nexus and Monero but my trust is fully with Bitcoin.
What do you think?
