ETH is good too but the presale price is quite high.
How can ETH presale price be high when the amount of generated coins in the genesis block depend on the BTC invested? If it was cheaper, you still would have the exact same number of BTC invested but more coins generated in genesis block.
Ok. Take a look at it from this point. In order to get x10 ROI with Crypti its market cap should be ~9000 BTC. To get x10 ROI with Ethereum its market cap should be ~100 000 BTC. What is more possible? One more thing. Investors' part of emission become less and less every day because of miners. All Eth investors are pretty much fucked up.
There is no question that mining will dilute the investment, but that has absolutely nothing to do with it being "expensive" as there is no fixed number. As for who will make more eventually, that totally depends of adoption and popularity. Bitcoin inflation rate first 4 year was like 35%? That didn't hurt early adopters becoming rich.
