If you are a small or new fintwit account that wants to grow your X page, you gotta start with good content first and foremost.
And usually that means something that can directly or indirectly help make your viewers money in one way, shape or form. A good analysis, take, prediction, chart, flow, and/or something you are seeing maybe others or the majority are not, etc. Added value. Alpha. Something that can improve the viewers own current situation at the end of the day.
Reply that to medium/big accounts or dm them and hope it catches wind with a reply or a reshare or requote or follow. And from there engage with them more. Then let the algos do the work.
That’s one way to start. But you gotta start. Be persistent, be consistent, be brave.
TLDR: Just give me a damn good pick and I’ll retweet you. Lol
