he went and sold his property to invest on Bitcoin without been knowledgeable about it. he went ahead and invest but loss everything because he doesn't know how to trade Bitcoin.
He sold all his properties and invested in bitcoins. Because he didn't know how to invest in bitcoins he lost everything.
Is it possible for someone to invest without having any knowledge, even though there are such types of people but the numbers can be counted on the fingers.
As long as your friend buys bitcoin and the amount is not intact, then the bitcoin will not be lost, unless he sells it shortly after the purchase is made. The exception that I said is trading activity.
The two types that you convey, the first is investment. Both trade.
What is the actual condition that your friend did that you want to tell.
Investing is different from trading.
