I invested like 20 bucks or so worth of BTC i had laying around. But after a week or so after doing that I really didnt have a reason to bump more in my account. I felt like just using the site as any other social media platform. If you think of it as a get rich quick scheme...it will just be another website you made an account for and forgot in a few weeks.
I was like that with twitter.. I made an account... left didnt come back til 3 years later and now i post there frequently. Steemit is something that takes time and with time comes it's rewards. But currently my investment is my comments i leave in others posts. Because no amount of money or anything can replace an honest comment/review/criticism.
I invest in being genuine with my posts.
Keep on rolling these awesome series. Love your 30 day challenge!
