Is my money sleeping? what to do?

I've just learned about NISA and now put money aside for it, but it's not as big as I would like it to be, 2Years ago I've set aside money on bank time deposits,The growth is so slow…

Can I withdraw it all and put on NISA? or is it too risky?I feel like my money is just stagnant and I'm worried that because it's just sitting there, I miss on oppurtunities that I don't know of.If anyone has any advice on where or what to do.would help a lot
