for example when you buy, send, receive, or trade Bitcoin, you experience how the blockchain operates and witness concepts like transaction confirmations, fees, and wallet management, Bitcoin is highly volatile in nature and engaging in actual investments helps you understand price fluctuations, market sentiment, trading patterns and how dip in Bitcoin can help you accumulate more with less price.
You've made some really good points OP but when next you're relating trading with Bitcoin you need to be specific on whether it's P2P trading that involves buying and selling or the trading that requires on to speculate about the price movement of the market, P2P trading is cool especially when the persons holding is due for profit taking, maybe they could just sell some portions via P2P on exchanges.
But the trading that involves market speculation is not something cool with Bitcoin and people shouldn't involve it with Bitcoin cause the risk is very high, one can speculate the market with other coins but not with Bitcoin cause it's very valuable and shouldn't be losed easily, Bitcoin is precious, it's scarce and should be held for longer time instead of trading with it.
