Then he would not be even interesting in trading, because he would think that only the bitcoin is holding by these people they can sell it at any time, then same in the case with other coins if Solana is hold by some of its team members or its owners then would you think that we are not going to trade because because may be its owner sell all the Solana and we may be in loss?
This is just the thinking of an individual, anyway we can't stop investing in the bitcoin just by not having proper knowledge about the trading and not having a way open up for trading in any coin.
Everyone has different desires in investing and there are some people who don't like investing in Bitcoin and this will not have the slightest effect on people who already like Bitcoin and they can understand well about Bitcoin and how they can profit from investing and trading on Bitcoin so they really like it and those who don't like it maybe they don't understand Bitcoin well and also maybe they have found a way to make money in another way which they think is easier.
