Problem is when I click on hide small/0 balances to see my alt holdings on these centralised exchanges it also hides my small alt balances that have values greater than 0 so I see nothing in my wallet overview.
Most exchange do this. Your dust tokens that is not above their hide small balance will definitely be hidden. But dont worry if the value of that token increase it will be shown again. You can always check all your balance on an exchange anyway.
Can you hold alts on Decentralised Exchanges and if so do you get the same email notifications from DEX's?
As much as I know you can on forkdelta you can store it as long as your wallet is still connected with the dex. But for some exchange like your uniswap, the transaction there is simple and automatic swap, you dont need to bid it and wait for your orders. Its real time value of the trading listed there. You can just connect wallet anytime.
Okay with forkdelta DEX I will get email notifications about delistings or coin swaps but my wallet must be connected to the DEX? That means my phone or computer wherever the wallet is installed has to be on and connected to the internet 24/7?
Why would you hold your altcoins to an exchange? if you have used an email to that cex then basically, you'll receive as many updates that they have including the delisting. But in dex, do they require emails? they don't, right? so you won't receive any update such as delisting.
The best thing is to be updated and check their blogs if there's an upcoming delisting. And for the display of balance, what exchange is like that? I haven't traded for long but when I visit exchanges, they only hide zero balances wallet.
So I can get email notifications of coin swaps. If I hold coins on my cold private wallet I will never get email notifications of coin swaps and will miss the coin swap deadline and if that happens my coins on my cold wallet become useless digital 1's and 0's
