Anyway, regarding long term investing and whether I should use Spot, Margin or Derivatives... My plan is to invest in loads of different coins/tokens but if we just use BTC as an example...
Before you continue trading or investing, of course you must understand the meaning/difenising of the three trades, as you said, namely: (spot, margin and derivatives).
Before that you need to know in detail what is called spot trading, Margin and Derivatives, for that you can understand the meaning of the three trades, below.The spot market or spot market is a market for buying or selling financial instruments, commodities, or other assets using direct payment or cash techniques. Therefore, the spot market is often referred to as the cash market.
Margin trading is a method of trading assets using funds provided by a third party. When compared to a regular trading account, Margin accounts allow traders to access larger amounts of capital so they can apply to their positions.
What are Derivatives? Derivatives are contract agreements entered into by two or more parties with the aim of selling or buying assets or commodities. Later, the contract will serve as the object of trade. The price of this contract value must be agreed by both parties.
After you understand the three trades, you can conclude what trading methods are worth using or long-term investments, I can suggest for you the right long-term investment method you do is the spot method.
Margin and Derivative methods are not appropriate / suitable if you use it as an investment method, the two methods that are the most appropriate for you to do are trading, because they have a third party.
