Bitcoin ETFWe can expect Bitcoin to reach $80K if the ETF is approved. Gold had a bubble and crash at around 1980, which looks similar to Bitcoin's 2017/2018 crash. However, after gold's crash of 1980, the price had an increase of 300% from the ATH in 1980. Applying this logic to Bitcoin, we can expect an increase to about $80K if we take its current ATH of just under $20K into account. I would not hold any altcoins if this is to occur as their value in Bitcoin will probably crash.

GBTC: Barry Silbert's ETFs are not acting wellJust a heads up, Mr Silbert's ETFs aren't doing well, and examining the holdings, each share represents only a fraction of a Bitcoin, and are currently trading at a big premium, so, better own coins directly, and leave the ETF alone. It can fall or lag Bitcoin's performance, based on this fact, and it's trading very thinly.
And, about ETC, I recently took a technical trade, but it looks like it is set to underperform BTC and ETH now, so I reccomend to stand aside from it.
This is a good summary of my thoughts about it too: www.huffingtonpost.com
Good luck,
