1. buy bitcoin at $1000 and get only BTC1
2. buy ethereum at $22 and get 45 eth
how much profit you get right now?
1. Current price $3935 which mean $2935 profit
2. Current price $289, which mean $12,000 profit. Can you imagine that?
That's why, that man argued that eth is best.
profit is important but not the most important thing. there are lots of things you need to consider. like how much risk your investment has. the risks of bitcoin investment is a lot lower than any other altcoin.
besides if what you explained here is all the logic you need to invest in something then i can bring 100 examples of things that are 10000 times better than ETH because they could have given much more profit!
example: HTMLCOIN!
it is literary a shitcoin. the value was 0.1 satoshi (yeah it was literary worth less than 1 satoshi) and went up to 15 satoshi. that is a 14,900% profit
your $1000 investment could have turned into $150,000
so with that man's logic HTML5 is the best investment!!!
