In a dreaded bear market that's lasts a long time, do you think that stablecoins are the definite solution for preserving one's investments?
So far, there has been a few stablecoins like Tether and NuBits which have gone lower than $1 at rare occasions. For investors depending on stablecoins as safe-haven assets against a bear market, this brings some disappointment. Still, stablecoins are able to retain their value against the USD most of the times. If they remain as is, then one could simply pour money into stablecoins to protect yourself against a long-lasting bear market. If prices for cryptocurrencies on the market go even lower than usual, you can even sell your stablecoins back into crypto to get more coins for your money. But this might turn to be extremely risky in a volatile crypto market.
What are your thoughts?

Definitely! When you say stable coins, you should also consider the volume and market size of that coin. A coin sitting at $4 for the past 6 months wouldn't be considered as a stable coin. You'd not be on a safer side with a coin that could have been fluctuating between 4$-$20. So an upper limit and a lower limit of the coin should convey its stability. Bitcoin is the best one indeed but would say ETH,XRP,NEO are quite safe.
