Nah... I don't trust that ad about earning by learning about crypto unless its a link from CoinMarketCap or trusted sources.
Now regrets... I don't see any reason for you to have regrets on this really, you have benifited by being in the Hive Blockchain.
I had my time starting over in Steem, which actually benefited, an angle supported my content and things grew...the fork happened... but it turned out good coz one can earn in two chains Steem and Hive...
My regrets in crypto...can be many(: ...stating to invest earlier, earn earlier, starting to diversify to other Alt coin investments earlier but you knoe what... I am getting better at finding good crypto projects and I check them out and am doing ok and growing in the space without any earn and learn crypto program...
So I am ok... my regrets are washed away, and I am hoping to use my learnings to make it big in the crypto space for myself...lets see!!
I don't have any real regrets...lol. I have learned a lot in the time I've been here. I am still learning and enjoying every moment of it. It's just a thought to throw around...thinking "wow, I could have been further on the journey if I started earlier".
No harm done.
Thank you for stopping by and for giving your input. All the best with making it big in the crypto space!
Have a great day!
