Here's a possible write-up:

"I'm thrilled to share that my investment in STX (Sky RokIt) has seen a significant increase! I bought in at $1.9050 and it has now risen to $2.1624, a gain of over 13%!

I invested $10 in the Bull Run and it's great to see my investment growing. The potential for further growth is exciting and I'm looking forward to seeing where this journey takes me!"

Let me know if you'd like me to make any changes!
