I'd definitely try the LoFi thing to boost views if you're up to it / it's in line with your goals for the channel. Do like an hour drive, or just slap some of the videos you have together to make about an hour. You want it to be something that people will put on and forget as they just vibe/work/study/whatever with it in the background. If you hired one of those companies to boost views, this is exactly what they do. The only difference is they have an army of accounts that they then set to watch that video a bunch of times to rack up views. The LoFi vibe videos are pretty popular though so search results alone should bring in views without the fake bot views. Please don't waste your money on those fake views though, growing naturally with people that will stick around to keep the views rolling is a longer grind, but it makes for a very healthy channel.

Good luck!
