the fall in the price of bitcoin which causes the coin to slow down to be registered in the market.
I have a Savedroid and Moneytoken , but it's very slow to list on the market.
does this happen because the market is weakening?

To get a coin or token on a exchange (market), a lot of money is needed.
Some projects do not want to spend money on this.
Thats why it sometimes takes a long time until it hit an exchange.
