If BTC not stop to fall, next buy could be below 200 or even below 100 sats.
I kept a few hundred thousands of my Sia and wait for the next opportunity to buy.
Keep in mind:
Sia project is one of the rare projects with a real value.
They don't are just another crypto, they have a product what can change the way the internet is working now. Most other coins out there have shit.
If BTC is stop to do this stupid things there easily can come a big bounce on Sia as well. Stay prepared and do you own research.
