As far as I know Types of traders:
1. Scalper: it can be done in minutes
2. Day trader: within 1 day
3. Swing trader: can be weekly to monthly

Traders focus on stock price fluctuations. The important thing is there are stock fluctuations/movements. So, technical analysis (patterns & trends in price movements)

Investors: long term. The focus is on company performance. So, the analysis is fundamental.

But I've also read an article, if you buy Bitcoin and hold it, you can say it's an investor. because traders and investors are the same.

Maybe someone below me can answer and give a better explanation.

Once you’re holding something that at a long period of time would yield profit then you are investing in that entity and you can be called an investor

 
I don’t get what you mean entirely but if you mean treating bitcoin as a currency then I wouldn’t call that an investment because you are not looking at gaining profit over a long term. This is even the first priority of bitcoin inception in the first place. The only person regarded as an investor is a longer time holders

Investing means you are looking to profit from that asset, as long as someone makes a profit from bitcoin, they are an investor. But there are still some people who don't see bitcoin as an investment, they see bitcoin as a currency, a peer-to-peer means of payment, and those who buy bitcoin for the purpose of spending cannot call them investors.

As I said, when you are a holder, a trader, as long as you are looking for profit, you are an investor.

You can be both an active user and an investor at the same time. If you own some amount of BTC, constantly spending and earning or rebuying a part of bit, but also holding some for the future, then you are simultaneously an investor and a user.

Outside of the US, a lot of people store their wealth in the US dollar, because it's more stable than their home currency. But they aren't typically called "USD investors". Technically, the same should be true for those who own BTC, because Bitcoin is a currency. But it's so fast growing that a lot of people buy it for the sake of making quick profits, which is easier to categorize as investing.

Everyone has their own way of understanding and explaining things. To me, Bitcoin investors could be considered anyone who has put in something, either their time or wealth, in order to acquire some Bitcoin. Wealth in the aspect of using their money to buy Bitcoin. Their time in the aspect of mining or any other means of acquiring Bitcoin.
 
You can only be called an investor if your acquired Bitcoin is still stored somewhere. No matter how little the Bitcoin is, there should be at least some of it to represent your investment before one could be called an investor, and if eventually all your holdings have been spent, the person should no longer be considered an investor but will now be referred to as someone who's invested in Bitcoin.

Investor is quite vague as a term, especially when you have short, mid and long term investors purchasing BTC for various reasons. Think of the way some people say ”I’m gonna invest in some gold”, does this mean they’re gonna “hodl” forever? It could be until tomorrow or for a decade. They may not even truly believe gold investments are worth the effort on the long run, but they’re shortly investing in it.

Investing doesn’t require belief or long term planning. If you want to invest, you just become an investor by buying BTC.

Investors are actually people who have part of the ownership of an asset. they deliberately put and hold the Bitcoin they have in their wallet for a certain time. As long as he owns Bitcoin, he will be an investor.
if you only have a wallet with no Bitcoin ownership in it, then he cannot be called an investor. because there really are people who aim differently in holding Bitcoin in their wallets for a fiat replacement. meaning they own the Bitcoins for the transactions they make. so he is a user, not an investor. even though they both own Bitcoin, we have to look at the goals they built for their ownership.

Investors are people who spend their capital to invest in Bitcoin and hold it a long time. What is considered as a long time?

You're an investor if you hold an asset for the purpose of holding(investing), regardless of the amount. That's pretty much it. It doesn't matter if you spend some of your bitcoin or not.

an investor, they are prepared to do long-term holding. so if someone has bitcoins in their wallet, it actually depends on that person's initial goal, whether he is going to make a long-term investment or will trade. but what is clear is that he wants to make a profit from keeping bitcoins in his wallet, no matter what method he takes, can be short-term trading or long-term trading, as long as he gets profit according to the target, then that person is successful
