The thing is, we don't know where the bottom of the bear market lies.
If you feel confident enough that this is it, based on some analysis (technical or fundamental) than go ahead. Bear in mind that it can go lower and than it shoots up.
Also, take into account that the BTC markets are being heavily manipulated since only 10% (in better days) is trading.
Who knows. The bottom line: it's speculation either way.
