Haha, so now the trolls are in an uproar because of the thought that Bitcoin maximalists won't even bother to hold altcoins because they know that such can be traded for as needed for day-to-day transactions?
Well they should be. Because Bitcoin is digital gold, that only has value that continues to increase because people to choose to hold it long term and not spend it.
Altcoins, not so much.
Trading BTC to altcoins "as needed for day-to-day transactions" is pointless. You will incur in more fees (exchanging, txs, etc) instead of avoiding them. At least until Bitcoin deploys LN and/or increase blocksize... but then it wouldn't be needed to use any altcoin.
So, in some way, this situation is forcing us to hold a higher percentage of altcoins than what we would be initially willing/comfortable to. Maybe that is even good for some people, or they think so because of the shorter term higher gains we have involuntarily experienced... but I don't think that is sustainable in the longer run.
