As of Jan 12 2021, GBTC, ETHE, ETCG, and GDLC have come down to reasonable premiums and LTCN and BCHG still have absurdly high premiums.
To understand why you have to understand some complexities about Grayscale products and who can invest and how they trade on market (especially when they are new). But long story short, if you are an average buy-and-hold investor or a newbie to crypto, stay away from LTCN and BCHG until they sort themselves out and their premiums come down if you are going to be buying open market. If you really NEED LTC and BCH exposure, look to GDLC or actual crypto or Robinhood for your LTC and BCH.
