I cannot comment on your predictions on Bitcoin price, as I don't consider myself to be a prophet (unlike you, it seems)

However the statement I quoted above is so naive... It just shows you are complete novice in cryptocurrency world.

Those "other cryptocurrencies" existed when Bitcoin was worth 20 times less, and they were worth almost nothing. Coins exist because there is a community around them, but not only as a tool for trading. Few of them survived periods when they didn't have an exchange to trade, some are almost forgotten, but still exist while there is at least a small community (especially this refers to PoW coins). You are just a trader, and you think like trader, without seeing other aspects of projects. Despite trading, there are lots of reasons to support a coin or develop it. There is a serious technology behind some of coins, and there is fun behind ohers. There is just a dedication and sympathy behind the rest. That alone will keep most of them running, despite of the price of Bitcoin.

These things are created by engineers, for people who love technology and love playing with it. What this even has do do with such things as 'price' is..?
