Bitfinex to introduce 100x leverage...
The Rogue Wave and coming nosebleed ATH and collapse of Core BitcOn (perhaps to ~$775 at the halving).
So we all need to move our coins to legacy addresses?
The downside to keeping hodl stash/cold storage coins in legacy addresses is that you'll probably have higher transaction fees when you finally move them.
The upside is that you'd avoid any potential segwit based attacks on bitcoin, like if miners decide to take all the segwit coins.
So, I guess you have to balance the estimated future fees for non-segwit transactions with the estimated potential for miner theft.
Miner theft would require a fork. A fork on which miner theft occurs would be of zero value, because there are plenty of ways that miners can steal funds, and no one is going to follow a fork of known thieves.
I hold 100% of my cold storage on Segwit addresses.
