He told that he sold all his coins because he wanna focus on developing Litecoin. However I dont think that. He sell his coins when the price is high and he got money very much. Dont believe what richers say
This clearly has some point for him to get nice returns, but if he believes in litecoin why would he sell it. In my mind thing that pops up is that he prob sold his coins or at least told us that he sold because he don't want to be seen as person who influence the price of crypto currency to take profit, since he is good member of crypto community that is well known.
Lets look what Roger Ver is doing for instance he bought BCH with BTC and is now pumping BCH, don't believe me? Check it for yourself on news or what ever he talks about. I do believe that Charlee don't want to be seen as just another influence that is doing everything for profit but that he is developing litecoin and helping out crypto community for other meaning. If he needs money in future I do believe that people will be more than happy to donate him, including myself for work and effort he had put into this community.
