I consider charlie lee as a wise man. I`m sure he took a look at the price chart before he sold all his Litecoin and found a perfect day for exit near the all time high vs. BTC. Telling people than he just sold cause he not like "conflict of interest" is genius! Think about:
Microsoft founder Bill Gates never felt this conflict, he even hold long time after he left the company. So do and did most people who build up a company. If a company owner sells his stocks, its a super bearish signal for this company. Normally. Not for super-genius charlie. He found something what people will eat like cake: "I, Mr. Charlie-Gandhi Lee, hereby declare that i just cash in millions or billions of $$$ just in YOUR best interest 😇" Cryptos more about trust than a company's. Decide for your own.
I would not even wonder if he switch to Bitcoincash. Its cryptos. He not must report anybody anything and it would not even anybody care or know. He can do whatever he want, nobody can control it. That`s the beauty about cryptos. So my advise: Use common sense.
