There is no lesson to take from the OP. If you start from
this post onward, you will see the OP is not telling the truth. He did not do a good job because the story is a lie, he did not sell his land for $17,000 to invest in Bitcoin and he did not sell the Bitcoin at ither $102,000 or $105,000 to reinvest in land and then buy more Bitcoin.
No doubt you did a good job by taking a risk. You took the risk because you know what Bitcoin actually is. I didn't have enough money to buy a lot, but I bought small amounts, which gave me good profits though. Bitcoin investment fully depends on the financial situation and knowledge about Bitcoin. Crypto is always risky; if we can't take risks, then we are unable to make money from the crypto market.
We can take a lesson from you to take the right decision at the right time. Actually, Bitcoin often gives us buying opportunities, but we have to accumulate at the right time. I am making some plans to accumulate Bitcoin, to be honest, so waiting for a right time once again. Your activity inspires me to think more deeply about Bitcoin investment.
