What blogging platform should I invest in?

I have used blogspot earlier. Used medium earlier. But now things have changed. I would prefer github pages with jekyll over blogspot, but personal blogs have limitations of audience. I do not have major social media accounts nor good enough followers. Just writing with no audience reach does not feel motivating.

Medium was going great but now it is behind the paywall. I am from India, Medium does not have stripe support here. I can buy membership but won't be paid for writing. Again motivation factor and amount is a little larger for Indian market.

I would write about technical topics, books and social topics.

What would you suggest and why ?
