#AirdropFinderGuide What does the buying-selling of crypto-assets consist of?

Some online platforms offer you to exchange crypto-assets for euros and provide you with a storage service for these crypto-assets. You can also store your crypto-assets on a digital medium called a "wallet" using a private key. If your intention is to hold them and wait for their value to increase before selling them, be aware that the value of crypto-assets fluctuates considerably.
