I am sure you are not new to the crypto world, of course you already know which altcoin is your target, and you only need other people's ideas just to reinforce how many people agree with you about which coins are suitable to be exchanged for your BTC, or you will keep it as BTC.

And I have read from some who wrote in this thread, many of my seniors showed coin number 2, namely Eth and honestly I also like Eth, if you want to halve the funds you have besides BTC you have to buy some for Eth.
