Bitcoin and crypto changed my life i earned so much because the fiat currency in my country is low compared to usd so i participated in bounty campaigns and i earned altcoins and bitcoins and converted them into fiat.
i was a student and i needed money and did not have much time to work so bitcoin helped me a lot.
Most of the people who invested earlier with bitcoin or any other altcoins in their pre-sales or public sale about 3-4 years ago, has now having a happy life with their decent earnings from last time, and not only that, most of them have gathered some experience on what kind of coins they will invest next time. I hope we can invest as well like them but today we have a thousand choices only a handful of them are true and legit projects.
