In this I support bitcoin because no doubt every person will support bitcoin, the king of cryptocurrency is bitcoin. One thing you should note is that Bitcoin is the only trusted coin where there is very little chance of loss if the investment is for long term.
Long-term investment only brings success to the top, and the world's largest institutions are holding only Bitcoin. But I don't support ethereum coin, if I have bitcoin because I can't think of any alternative but bitcoin.
Yes, we are in the bitcointalk forum for a reason and not ethworld, because bitcoin is a great coin and there is no other coin that could do as well as bitcoin could do. I understand some people may have their doubts and they want to make more money but that doesn't mean that bitcoin would be a same thing to beat, we are not going to see that easily. At the end of the day we are not going to grow at all, we need to focus on how to make some money with whatever we do, and for that to increase well enough we need to focus on how to make more money.
I am sure that we are going to see people have a look at altcoins a bit closer these days because they hope to make a lot more money, as in literally get rich enough to retire with this bull run, and to do that you need to invest into something other than bitcoin, but that's not going to be ETH neither, so ETH is neither as strong and good as bitcoin, nor as profitable as some altcoin.
