It would depend.
If you have $2750 fiat, then the smart thing to do would be to enter at $2k each and get 1.375 BTC.

If you have 1 BTC then the USD value is irrelevant to your BTC/LISK trading pair and you need to focus on a good entry relative to the pair you're trading. Current price is about 72k sats (.00072 BTC each), so if you'd entered at that price with your full BTC, you'd get about 1,389 LISK. You wait a bit and LISK rises in value relative to BTC, say 5%. So you "capitalize" on this gain by moving back to BTC, but now you have 1.05 BTC.
You see that LISK has moved back down, so you buy back in again, for simplicity sake, we'll say its back to 72k sats, so this time your 1.05 BTC buys 1458 LISk. You wait again and it raises 5% and you go back to BTC again, this time you have 1.1025 BTC.
So you'd have gained crypto, no matter how you look at it
1.1025BTC >1 BTC
During this time however, BTC could be up down sideways to the moon, whatever. That doesn't matter until you're cashing out.
If you're not gaining BTC, you shouldn't trade alts, because it's more advantageous to stay in BTC if you're not focused on gaining BTC value.
