Is it too late to start buying alts?

I have stacked quite a bit of BTC and ETH when they were at their ATLs, but since then I have stopped investing since I moved to another country and I took a long time to understand how taxes work and how to pay them etc (used to live in a crypto tax heaven).

I want to start buying alts again to grow up my porfolio faster and rebalance it with the profits of BTC, but it seems like the best time to buy them has already passed and it is incredibly risky to buy now.. By the way, I usually don't buy small cap alts, but mostly those with either a strong narrative or Layer 1's / Layer 2's who are still actively building.

What are your thoughts? Should I go ahead and start building a position on Alts?
