From my research I have gathered, despite people treating the market like it is a bubble, because BTC is programmed for scarcity it has to continue to rise at this point in order to still be mined. The power cost to mine it is extreme and is just going up more in the future. I see it as the main portal coin and it will remain on top because no other coin has the infrastructure BTC does. I see other coins being used for micro payments, the huge fees will just be the cost of entering or exiting the digital economy. ETH is a token, not a coin few people see this, but we all see now that a token has trouble scaling. If BTC has any major setbacks LTC will step in, it is the only coin with potential for flippening in my view.
