Partial Shares

Why can't I enter a partial share for bitcoin's on the stock quote section of the Seeking Alpha app or website? It does not have a decimal point to be able to do that. I am sure I am not the only one who has bought a partial amount in Bitcoin. The system only allows full coins so the numbers that total are far off what they could/should be. I ask that you put a decimal button on that share count section so we can see the actual counts and amounts. Otherwise I cannot use it for them. Since I own more than just those coins, I would not need to be at seeking alpha if what I was looking for could  found together elsewhere. I came here so I would not need to go to alternative sites.
