Do you guys think I should sell all my BTC and buy BSV?

Not all but more than half.

i sold a large portion for sv over the last couple days. liquidated a few alts as well. i am holding some btc still in case of a huge exit pump

In my humble opinion; yes.

Be on the right side of history in the making.

Hang out around here long enough and you won't have to ask questions like this.

I sold all my alts and most of my BTC for BSV. Went all in at the top because thats how I roll. This is not financial advice.
