I do not think any of the crypto hold any long term security. Set a target reach it and take some, repeat the process. The longer it lasts the more you earn. Eventually, every thing will go to organised finance. This is inevitable as there is no ambition within or outside of the crypto-sphere to create and alternative currency to that controlled already by financial institutions.
Look to the simple influence a government can do to a currency of crypto. The decisions made on a countries finance comes with recommendations from the banks. Each time you get 100 take 10 out, you can keep growing and building something toward a rainy day.
