IRS taxes and FIFO, setting aside Long Term positions

[abercrombie]

I don't know much about taxes.  But I was poking around and saw a thread where some suggested use of FIFO.

From last week's dip, I have some BTC in the 300's I'd like to keep as my core long term holdings (or until the next dip).

Since I buy and sell often on nearly a daily basis, is it possible to set those aside and consider those my Long positions?

Hope this makes sense.
