I think it is possible @stackin... Removing your delegated SP, you have around 3000 odd SP. Reaching 50,000 would be to grow roughly 16 times your current size.

I grew from 0.245 SP to 450 SP in seven odd months. That's like 2000 times nearly, right? Of course, you can do it faster since you have some momentum already going on and it appears that you are motivated...

I give you a "Thumbs Up" for your initiative and believe you can do it! All the best!
