What type of crypto wallet do I need if I’m starting with 10-20 million VND?

A hot wallet is sufficient for this amount. I recommend Trust Wallet (mobile, multi-chain native, Vietnamese UI, Binance integration). When your portfolio exceeds 50 million VND, upgrading to a hardware wallet (Ledger Nano S Plus $79 minimum) becomes mandatory.

Where is the most reputable place to buy a Ledger in Vietnam?

Buy directly from the official shop.ledger.com. Do NOT buy from Lazada, Shopee, Tiki, or Facebook third-party sellers — the tampering risk is high. International shipping to Vietnam takes 7-14 days, customs is straightforward. Shipping costs ~$15-25 USD.

If my hardware wallet is lost or damaged, how do I recover my funds?

The 12-24 word recovery seed phrase is your backup. Buy a new hardware wallet (any BIP-39 compatible brand), enter the recovery seed phrase = funds restored. This is why the recovery seed phrase is most important — protect it carefully with cryptosteel + safe storage. Losing the hardware wallet is fine, losing the seed phrase means losing your money.

Do I need a multi-sig setup if my portfolio is under 1 billion VND?

It’s not necessary. Multi-sig adds complexity and cost (multiple hardware wallets) and is only economical above 2 billion VND. Under 1 billion VND, a single hardware wallet with a strong PIN + cryptosteel backup + secure storage location provides sufficient security.

What happens to Trust Wallet if Binance is affected?

Trust Wallet is a non-custodial wallet. Funds are on-chain, not on Binance servers. If Binance faces issues, Trust Wallet’s code remains open-source and available. The recovery seed phrase allows you to migrate funds to any other compatible wallet (MetaMask, Phantom, etc.) at any time.
