If you like a coin don’t trade against it, that is IMO the most healthy opinion one can have.
That’s why I only trade to get more Litecoin, never to have less.
If your strategy was to own more bitcoin instead of LTC you would have 4 times as much value in your portfolio right now if you had bought in 2017 when BTC was $950 and LTC was $12. From that point on you would make four times the growth in value at today’s prices. LTC is for spending, BTC is for holding your life’s hard earned money.
