This is bitcoin maximalist mindset and there's really nothing wrong about it the guy just want to get less pressure on his invest that's why he decide to invest only on bitcoin since we all know that there's more potential to gain especially if know a lot about what strategies for accumulating is really convenient or working for us. But for other people maybe for now they still trying to explore their selves on those shitcoins that's why they still add this on their investments. But if they lose a lot and could able to know that holding bitcoin is more better option then for sure that they would join a lot of people do this hodl movement for long term profit gaining.
