CURIOUS FACT
Sure! A curious fact looking into the future of cryptocurrencies is:
Bitcoin will reach its maximum limit of 21 million coins around the year 2140.
This means that, from that moment on, no new bitcoins will be mined — and miners will only be paid for transaction fees. This change could completely transform the economy of the Bitcoin network, creating new challenges (and perhaps new revolutions in the system).
Few people think about this because it seems distant — but the effects will begin to be felt much sooner, as the miners' rewards decrease with each halving.
