Bitcoin may be worth 100k$ around 2025. Then maybe we can earn from Bitcoin. And we can go further in agricultural development.
I mean Bitcoin really is a great investment and he gets lucky in believing in Bitcoin when he bought it, As a farmer its difficult to get in information on the internet and his friend was really kind in teaching him about it, and he really got it since he believed on his friend advice to invest on it. I mean if you think about it your uncle probably wasn't really into new technology at that time so he's really lucky to even bought Bitcoin at that time.
For sure bitcoin will be big on the next Bitcoin halving event and I really think that the 100k$ is realistic for the next bull run, especially after the Bitcoin halving event, I just after bitcoin halving a lot of institution, banks etc is going to invest on bitcoin as well and that is what is going to boost bitcoin momentum pushing its limit and surpassing the all-time high. As long your uncle already going to earn a fair profit on this bitcoin he could already sell it at any time, but he should wait for the next bull run to see and test what is the best price to sell his bitcoin. Also, other farmers should not be greedy thinking that they might be lucky as well when they bought bitcoin, cryptocurrency is still a risky investment.
