For me, no reason to hold multiply altcoins if you are not 24/7 trader. The philosophy is in quick sell of tokens that shows growth better than Bitcoin.
I belive in Komodo. My portfolio is Komodo+Bitcoin
we need to adopt the coin swap sometime base on the state of the market and altcoin, trading strategies differs base on what works for you but we need to manage our greed to prevent being trapped . For any coin held, one should have an exit price target and move the profit to other venture.
