Move everything into BTC or keep my Alt spread?

I exited the majority of my positions a few years ago at the peak and walked away with profit I was happy with.

However I kept a portion behind that reflected my original spread just to play the market. Safe to say I am seriously down across the board. I used to care plenty about crypto and was pretty active reading into the news and keeping up with projects, not so much these days.

AVG buy in and portfolio %:

BTC – £0.00 (Mined) – 28.25% ADA – £1.09 – 35.15% ETH – £2140 – 15.31% VET – £0.09 – 14.21% DOT – £15.91 – 6.79%

BTC may see a new high this year and it may not. In your opinion should I keep my spread as is and let the alt-coins have a chance to catch up with BTC in the event of a Bull, or move all into BTC and see how much I can recover from the remainder of my initial investment?

Cheers.
