Buying bitcoin by selling land is very risky because sometimes bitcoin shortages sometimes go down, I'm not sure this is a good idea, but you've sold the land to buy bitcoin.
I suggest you hold your bitcoin because now the bitcoin price is down again, wait until the end of the month for the short term, if you do not need enough money to hold it until the end of the year, you will get your kentungan.
If we look at the chart of prices of bitcoin from the past years since it was introduced, it rose up to an extraordinary high value. It lead the crytocurriencies world for many years. Now if someone just sold its land to buy bitcoin, I don’t think he has made a decision which he is going to regret after some years. Because of the fact that the values of bitcoin showed an increase of about 200%.
I appreciate the decision that man made to sell his land and I don’t think he will be in loss, all he has to do is to wait while the prices are to the top again.
