i think it is, because in the year 2011 you can buy a Bitcoin for only 4$ and if you buy 100 Bitcoin before and you still have it now , then you are a millionaire , and if you buy bitcoin now it's late, because the price of BTC now is expensive
From the past you can see the power of bitcoin, which continues to increase year by year, and the future bitcoin will also increase. I guess you are not too late to benefit from bitcoin.
