there is nothing called "token" in bitcoin. there is also nothing called "bitcoin" or "coin" that you hold.
in your wallet you are just keeping "keys". the coins are the transaction outputs that exist on the blockchain and depending on the wallet type you use you may have the full blockchain or just the headers.
and there is virtually no limit to the number of keys you can keep. but practically when it grows to a very big number you may start experiencing slowness.
In connection, I recommend that you should divide your bitcoins and store it in a different wallet. Your bitcoins might be put at risk if you all your eggs in one basket. Let's say in this wallet you'll store 10 bitcoin then keep your keys and again you'll make another wallet for another storage of 10 bitcoin.
P.S. Nevermind the 10btc since its just my example. You decide as how much will you split or divide it.
