Invested my first $250!

Hey all, I’m new to this world and while I’m learning a lot, I have some questions!

I recently put $250 AUD into bitcoin for the first time using CoinSpot. I read up on hot and cold storage and invested in a Trezor model one for storage.

I’ve now realised that CoinSpot charges 0.0005btc per withdraw which equates to about $50AUD.

Should I keep using g CoinSpot for now, stack a little more (thinking 1k) and then withdraw so it’s not quite as big of a chunk, then move to a different exchange? Or, cut my losses, move the funds now, eat the fee and start with a new exchange?

TIA!
