I think in the crypto world there is no difference, an investor invests based on valuation and usually holds and plans longterm, a trader usually invests reactionarily based on news and recent events to gauge the price.

Well you can't short in most exchanges here, and even if you could I would not go into margin trading, it has too many risks by itself. The crashes here are very soft, and you have to be a big cowboy to short a bullish market overall.

So a trader here basically just buys at dips and sells at the top, while an investor just buys and holds. So a trader is hunting the variance in the price, an investor the longer trend.

But it's all in the same context since it's an overall bullish market, both profit from rising prices.
