Do you immediately transfer your crypto to your crypto wallet after trading?

Do you immediately withdraw your crypto after you trade and transfer it to your wallet? For example, if I bought ~370 shares of VET (worth $10 USD at the moment), do I transfer it right away? It seems like the most practical way is to not transfer right away because there is a transfer fee. Transfer only when the amount is large, such as maybe worth $500 USD? Beginner here, so advice would be greatly appreciated.

I tried transferring from Uphold to MetaMask and there is a fee with the transaction.
