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.
