I basically stick to idea buy low priced coins like 0.00001$ that have good potencial
so when coins get to 0.01$ its a very good profit of %
For my self i have 60% of assets on BTC
But i wonder on which coin you have more % invested ?
It has always be advisable not to do more than 10% size of your Bitcoin in any other although you can do whatever you like it is your choice, Bitcoin has proven to be the best coin and it has more solid foundation than any other coins, so answering that question that which coin one should have more % invested on should simple be coin and not any other coins.
