In 2010, one Bitcoin was just $0.20, and buying 5,000 Bitcoin would cost only $1000.
Compare that price as of then to today's price $27k plus, you would be obviously filthy rich.
Thats true, because the same way Bitcoin is currently at $28k per BTC now, so in the next 10years this same price likely to hit $100k per BTC, and as such, it's never too late for anybody to invest in Bitcoin, inasmuch as you can afford it, and as time goes on you keep on increasing your portfolio by buying more either weekly or monthly, of which I assure you that if only you can do so, in the next 3years, you will be amazed how many BTC you must have accumulated. Far more better than saving your funds in fiat currency in our traditional banks, of which constantly prone to inflation.
I am also optimistic about the future of bitcoin and expect it to rise many times higher than its current price. I support you or others accumulating bitcoins by day, week, month...but I think it's not entirely wise for us to focus on accumulating bitcoin and ignore fiat savings. Because bitcoin is an investment and involves risk, there is no 100% guarantee that bitcoin will continue to exist or will increase in price in the future. We need to think about those risks, don't be too subjective that bitcoin is absolutely 100% safe. A savings account or diversification is essential instead of just focusing on bitcoin.
