As long as you're comfortable with your LTC/BTC move, then peace be with you!! I think diversification is really important, and having some of the kingpin of crypto as a baseline will probably be worth the while, but we all know that crypto is nuts and anything can happen. Leveraging the price action to accumulate more net tokens is brilliant. I should do that, but I don't touch my crypto really in fear of making a mistake. I made one big mistake in the past and never want to do that ever again, so I avoid it. I will probably build a little trading portfolio for fun and to challenge myself, but my core remains offline.
As for amount, I keep that private. Let's say it's between 0.0000001 and 1,000, ha. It's really important that people don't specify that publicly for safety reasons.
