Can small coins be vanished from trading?

Rates are in indian rupee
I see lots of coins with small prices like bittorrent.
I have seen some YouTube videos that bittorrent can go upto 1$ in timeframe of 2023. Have seen videos of other smaller coins as well.
I was thinking to buy some smaller coins and forget about them.
At These prices is nothing to lose. Right?
I was considering a small amounts which I can afford to lose.
I think if any one of the coins out of lowest 5 coins hit can be a jackpot in let's say 5 years.
I wanted to know what are the chances of getting all coins vanished from trading.

The price is set by the market participants. What you see in apps or exchanges is an average price of all users. If nobody wants your coin, then yes .. it is worth 0. It can happen. You don't find anyone to sell to.

You still own the coins. They don't disappear. It's just that nobody will give money for them

When you buy coins on defi exchanges ( pancakeswap or sushiswap) you have to watch the liquidity pool how much is in it and are lp tokens locked or not or are they send to a burn adress.
If the deployer is able to withdraw his lp tokens you have to be carefull

lot of exchanges is shit, and when coin going up they block it.

That is not something impossible but for all small coins it will be rarest or rare case. Just imagine food items like grocery and veggies they are in SUPPLY in the market because there is a DEMAND for consumption. Same is the case with crypto coins their prices vary according to the demand and supply in the market so they can only vanish when it's No Demand & Supply. Just like it's unlikely that people won't stop eating it is unlikely that all those coins will vanish.

BTT can really do good in long term. I also hold some.

seeing dodge on that list almost makes me throw up ughhhh
