Everything in one watch-only wallet ?

Hi everyone,

I've got some bitcoin there, ada here and other coins elsewhere, the thing is I can't have (or can't find) a watch-only wallet that can allow me to have everything in the same place.

It's probably something technically impossible but I wonder If such an app or something else exist (didn't find anything for now) Even if it's something simple where I just input the amount of coins I possess and it calculate the price in USD based on the price of the coin.

Well, if you know something like that, feel free to share, thanks

Edit :

I'll probably go with CoinGecko, thanks everyone!

So far I had these suggestions : - CoinMarketCap, does what I want, not a fan of the UI and when I enter some coin price in my transaction and save it, the price is automatically changed to something higher or lower, weird (but I could be the issue tho)

• CoinGecko, does the same thing as the previous one but I prefer the UI, there's a better access to the transaction, once the coin price is set it don't move.

• Block Monitor, didn't try this one for now.

• Delta, the Dashboard app, Dopamine, Zerion, Coinstats, didn't try these ones either for now

• CoinTracker, not the main purpose of the website but could be used as a portfolio apparently, didn't try it. Keeping it in mind for the tax helper

• Using classic tracking crypto website to track my wallet, as last resort

• CryptoPro, can't try this one as I'm on Android
