In my opinion on the cryptocurrency market there is a need for stable coins for the safety of investment and profit-taking when trading on exchanges.
Right.
Quoted from #64: "Cryptocurrency traders can reduce their exposure to Bitcoin by selling their Bitcoin for stablecoins. This allows traders to keep their wealth on an exchange without converting back into fiat. This is useful for two reasons.
First, many exchanges take days to convert fiat into crypto, which means investors must wait to trade.
Second, converting back into fiat means a tax bill is coming soon, since most exchange on- and off-ramps now require KYC-AML."
The number of stable coins will soon increase, because each country will create its own state coins, which will be backed by national currencies.
Indeed.
All cryptocurrencies issued by Govs will be Stablecoins, as they will be backed by the national currency.
But also all cryptos issued by the big financial corporations in order to settle their transactions between each other, are all Stablecoins:
"Interbank settlement is a trillion-US dollar industry, as discussed in the chapter on Ripple in the June 2019 edition of the Crypto Research Report published by Incrementum.
Instead of giving away billions in revenue to Ripple, companies such as J.P. Morgan are releasing their own centralized stablecoins backed by fiat in order to settle transactions globally on a permissioned blockchain instead of legacy banking software." (#64)
Shops can't use currencies that are too volatile.
This problem was mentioned talking about Facebook's Libra.
Facebook does not want to experience losses overnight due to the effects of its unstable coin price.
That's why, if businesses will start using cryptocurrencies on a large scale, it will be Stablecoins.
Finally, people looking for an alternative currency because their national currency is subject to fast depreciation (high inflation), these people can't keep their savings into cryptocurrencies which are volatile.
They can't afford to lose 50% of their savings due to the volatility of the cryptos they converted their savings in.
"People in countries with high inflation and hyperinflation can hold on to stablecoins in order to preserve their savings. Bitcoin is too volatile for most people in Venezuela. Instead, they would prefer to hold onto cryptocurrencies backed by gold or Swiss francs." (#64)
