From a "lets make the world a better place perspective" should we support only bitcoin right now or altcoins also?
Who is 'we'?
If you want to miss out on opportunities that currently undervalued alt coins present, sure, don't buy them, buy them later when they are more expensive

That doesn't say all alt coins are ok to buy. Do your own research and due diligence.
To clarify, we is basically everyone in the crypto community currently.
I have alts yes but that is for selfish gain, im talking about whats best for the world politically.... some have said they prefer everyone focus on BTC right now - Im not sure & need convincing of this argument.
Well, maybe because of the reason that Bitcoin is the most and first to be recognized cryptocurrencies amongst all out there that is why the issues regarding the use of cryptocurrencies only surround in bitcoin. All controversies pertaining to Bitcoin are being debated many experts in the field of economy saying that Bitcoin is a bubble and we all should be careful about investing in it. We are forgetting that there are still a lot of altcoins that are undervalued that also needs to have the same attention and the same way we value Bitcoin. It is only that we can't see the potential of altcoins the way we see the potential of Bitcoin.
