if i have 50k should i rather invest in bitcoin?

I'd say learn about Bitcoin first. Try a demo account first and check if you can handle the movement in the market. If you think you can, then go for it. But I will still suggest to try spreading that amount to different coins.

That's right. You can also start by getting a partial amount from the 50k first and try investing it on Bitcoin. If you think you can handle the market, then you may opt for investing everything on it. Or as Sendo has suggested, spread it to different coins.
