To a fresh newbie it is very hard to explain a topic like crypto , how they are issued , the decentralized nature , what effects the value , how to trade using the fluctuating value , the transaction fees and many more  things , for explaining  that to a newbie we must have our own concepts clear about legality because its the most asked question , well if someone just wants to invest they should not need to know about the microtransactions using blockchain , just briefing is enough ,
