we are so early

hypothetically speaking say I had $30M worth of $Wif and proceeded to market dump it all in one clip while also having a max leveraged short open on an exchange.  

1) would this work? 

2) Is this legal? 

3) If not how much jail time would I face?

Great question... ive thought about this many times and as soon as I get myself 30milion I'll let you know how smooth this works
