What about security within exchanges?

Cryptocurrency is not backed by any central institution, and your cryptocurrency holdings aren’t protected the same way as money in the bank or traditional investments. Some exchanges, like Coinbase and Gemini, keep any balances in U.S. Dollars you hold with them in FDIC-insured bank accounts. But FDIC insurance doesn’t apply to cryptocurrency balances.

To protect your crypto, some exchanges have insurance policies to protect the digital currencies users hold within the exchange from hacking or fraud. Coinbase, for example, has an insurance policy worth $255 million. That means if Coinbase’s reserves were hacked and any amount of crypto up to $255 million was taken, account holders would be protected. Others, like Kraken, rely on their security practices to protect clients rather than insurance policies.

Currently, I am holding most my coins on EQONEX's platform, as it also allows for quick and easy staking with their EQO coin. As far as I am aware, EQONEX is the only Nasdaq-listed company with a cryptocurrency exchange. They have secure regulations in place, meaning that you enjoy a good deal of security. There are coins being listed on NASDAQ like EQONEX's EQO coin. Since these coins are backed up by one of the biggest listers, the trust people are placing in these coins are high. Don’t waste your money on exchange apps just because they are well-known or whatever, always do your own research!
