Mercado pago gives access to exactly 6 cryptocurrencies. Which should I invest in?

Mercado pago (a popular finance and shopping app in Latin America) offers users the ability to buy and sell exactly six different tokens. It's a pretty limited selection, but for many many casual crypto dabblers in this part of the world it's their only access to crypto. I use it occasionally because it's integrated seamlessly with my bank with essentially immediate bank transfers with no transfer fees (don't feel bad for the poor altruistic founders though, they'll scrape by with the 1.5% trading fees ????). Between these six, which token do you think is the best buy for the coming bull cycle: BTC, ETH, LINK, USDC, LTC, or UNI?

I've got my bags of BTC and ETH for the long term, but I'm leaning towards LINK for current-cycle gains. I don't know anything about the potential of UNI.
