Maybe this time is not bad enough to sell it now. Coins are in the green zone this week. But if you want to wait a little longer is not a problem, because it seems like market conditions are pretty good.
Yes. But it depends on the coin or token that you have. If that coin have a great opportunity to rise in the coming months or years. It is better to hold and wait for the right time when the price can achieve the expected amount you want. And if that tokens are not popular in the market. It have a less opportunity to rise. It is better to sale your token when the price are high to gain a bigger profit.
