In most cases, yes. Lenght of holding in the major difference between investors and traders.
But then I guess an investor could be considered a trader as well, based solely on their actions: they buy and they sell, right? They could buy for their retirement portfolio or .. they could buy now and tomorrow, if BTC dips to $5k, they might sell out of fear. Why do you think there's not much of a difference them?
I agree, that's the reason I included in my initial reply, that this checks out in most cases. In the end everyone wants profits, if I invest in Bitcoin and set a target of 20% ROI, if that hits in 24 hours, I can take profit from my investment, without having to wait for a long time.
I'd take it another way to differentiate the two: traders follow charts, investors follow potential.
This also checks out
in most cases, traders can sometimes get involved with potential or the fundamental analysis of a currency they're interested in trading, this could be a news or update on the project which could have a direct impact on the market price.
Investors also can consider charts, or technical analysis when putting their capital into a currency. This could be used to determine the best time to buy, which ideally is the bottom price. For example, if I plan on investing in BTC, and use technical analysis to predict a drop in the coming days, I could hold on my investment and try to catch the dip, to maximize my potential profit.
I can say that there is sometimes an overlap in both concepts.
