Recommended to transfer btc/eth to cold wallet every time I bought them?

Hi Anon,

Like what Chris said, you'll need to consider how much crypto you're holding, but not just due to transfer cost as it may affect your opportunity cost too. By keeping your crypto in cold wallets, you may lose out on the opportunity to earn interest on your coins. Another pointer to note is that generally cold wallets are used for large holdings of crypto (in my view it would be a few hundred grand). If your crypto holding is ~100k or less I think leaving it in a hot wallet like Gemini is fine as the security should be good enough. Still, if you're worried about waking up one day and discovering your coins are gone then I'm sure transferring them to cold wallets will give you a peace of mind :)

Hope this helps!

I think it depends on how much you're buying each time. Since there are fees that are paid everytime you transfer in and out of your cold wallet, if your purchase size is too small, you may be losing a significant portion of your investment on your transfers. But yes, if you're a buy and hold investor, then a hardware wallet is the ideal setup for maximum security.

You are also right in that you will have to incur the costs in order to transfer them out and sell them. To get back your SGD, you'll have to sell on a platform that supports crypto fiat conversion such as Gemini, Binance etc.​​​
