With buying securities I believe it's easier to sell however if you buy bitcoin itself or for example gold or silver who is going to by the physical or crypto currency my statement is : I believe buying a security made up of bitcoin companies is more liquid than buying bitcoin itself. I am fairly new so my sentiment on this could be off. But if bitcoin is at 5k in 3 yrs who would buy it however if you have a security and it doubled from when you bought it it's more likely to find a buy IMO
