Sorry to say this but I can not except most of your words. Putting all your money into one coin whether it is bitcoin or some other crypto is the worse case  scenario for the any investor. Please, read the following article to learn how  "portfolio diversification  minimizes the overall risk of the portfolio."

OP is correct stressing  on  plenty of noteworthy coins that can be added to portfolio. Some of them have  surpassed  bitcoins in  both technical and structural way. A world where bitcoin would be the only idol that needs worshipping were barren of ideas world.
