Holding Bitcoin in Revolut

I’m relatively new to Bitcoin, have around 300 dollars worth which, at this present moment, is up by about 20% since I first started buying. The problem is that I’m pretty IT illiterate and it’s all held in Revolut- is this a problem? Where’s the best place to hold it for someone who is not very tech savvy?

I lost all my shit coins when FTX went bust so it’s got me thinking that maybe Revolut isn’t the safest option either!

Any advice or pointing me in the right direction is hugely appreciated!
