Both trading and investing are the same way and destination to get much profit but have different system how to get much money with bitcoin and altcoin, with trading we can earn much money every day and investing could earn but need waiting for long term.
Both will be considered as an investment, but the thing will be based on our assumptions. Each person will have a different view about the trading and investment because some people will always for the long term investment, so people who wait for the long term will always get the benefit through their investment.
These two is interconnected with each other.
When we invest, we also do trading. For example, we want to buy a cryptocurrency, let's say Bitcoin. What we will be doing is to buy it through exchanges or maybe convert our fiats to it, we are exactly doing trading and the fact that we are doing it is because we are investing in it. If we will be talking about the long term, that means they are investing and will be trading in the end.
