If I do not agree because if you trade with bitcointalk you have a small capital just the same as lie because with your small capital Do not get a big profit but if you do trading in altcoin you will be faster can profit and a little more because you have small capital.
It depends on what coins you have, if you have ETH then I don't agree selling strategy. But when you refer it to other coins with low value, I think its good to trade and buy btc or ETH because both have bigger value or increase of price and you will gain huge profit.
