While Bitcoin there are a few scaling options, it appears that a number of Bitcoin investors have been switching to Altcoins, and may not switch back to Bitcoins any time soon .
What will happen if investors continuously switch to altcoins? Will bitcoin crash ?
You have a point that many investors are switching to altcoins because of its new features, ETH was an example of those altcoin mostly swtiched by the investors, after it's split, it made a huge comeback and now following bitcoin to it's price, the problem is, bitcoin is still the same as we know it, it needs to be improved, high fees and slow confirmation, that is the problem.
