Small amounts can yield massive results if you stick to the course and let compound interest works its magic. Let's get it! A lot of people think you need to buy an entire Bitcoin to invest in cryptocurrency. Most crypto exchanges allow you to buy fractional Bitcoin with small dollar amounts. For example, Coinbase has $2 minimum BTC purchases so you can dollar cost average your Bitcoin over time. As a long term Bitcoin HODLer, I believe it's a good idea to buy Bitcoin ASAP. Global Bitcoin adoption is getting bigger and every day is an opportunity to invest in Bitcoin before the price goes to the moon. If you hold long enough then I believe it's possible. The truth is it may take 15 to 20 years for a $100 BTC investment to turn you into a US dollar millionaire.
