Wanting to invest in the exchange's native coin is an option, but if you look at tier 1 exchanges like Binance with BNB which was originally still under $50 but now reaches ATH $700++, of course the coin makes quite good profits.
It is undeniable that native coin exchanges usually provide their own benefits for investing, especially if the exchange is really increasing, top exchanges. But once again, you really have to be careful in investing in exchange coins, because we also have to understand what kind of exchange is likely to have high potential to increase too. So yes, there must be certain considerations. However, if it is a top exchange, it might provide quite high benefits and potential, as long as the exchange is still operating. And usually when we have the coin, there are many offers and discounts from the exchange by using the native coin from the exchange.
But yes about storage it is not recommended to use Exchange storage because we do not have full control and about SAFU funds this depends on each exchange.
Exactly, especially for long term, it is not recommended to store in exchange wallets, it is quite risky. However, if for short term and especially trading, yes, inevitably in exchanges to save transfer fees. but it is better not in too large an amount.
