The second decision you must make is how you will fund your account. Many traders/investors choose to begin in the cryptocurrency space by linking their bank account to their exchange. Then, you can deposit your local fiat currency onto the exchange. The amount you choose to use should be at least 1000 USD.
A less popular option is to link your debit card to an exchange, but this is not advised as it can carry potential fees.
Never under any circumstance link your credit card to a cryptocurrency exchange. Doing so will likely raise many red flags with your bank and could lead to unfortunate complications in the future.
If you hold a cryptocurrency from another exchange, you can send that to the exchange you just joined. Additionally, before making a deposit onto an exchange you should also search for any promos/bonuses that the exchange offers that you could opt into before sign-up.
