I think for the bounty hunter there is no need for the KYC regulation to be passed. Because they have very little amount of token as a reward they get. Most of the bounty doesn't require the KYC but some are required this and by getting their data they manipulate this. May be this later become the birth of the financial fraud.
The bull and bear is the two phases of the every market. So, wait for the right time the cryptocurrency market must stand up again in the next year. As, we know only two phases so, now is the bear running so the next will come bull and this time the price of the cryptos will go sky rocket.
Still now I have been using the Myetherwallet as my best wallet for storing the Ethereum and the ERC-20 based token. Since last two years I am using this but one demerits of this wallet you can't change your private key even if you account has been hacked. So, If somebody has any better solution to the MEW then tell me.
In the cryptocurrency market there is no coin that we absolutely say it is a top ranked coin. Because every coins are crash severely when the market go down tread and every coin also increase in price 50x to 100x and even more than this if the bull market is coming and running. But, the coin that are never listened of it's name is benefiting more than the top rated coin. So, I always search the newly listed coin to bet.
Yes, ICO should be regulated but how it will regulate is the matter of consideration because of decentralized and anonymous nature of transaction of the token. But, if any private body will strictly regulate the ICO with scrutinizing the project then most of the fake ICO will not come hence the investors money won't go waste.
The hacking of the coin these days is increasing from the every source whether it is your Myetherwallet or the exchange account. Nothing is secure. Also, the hacking from the exchange the coins stolen doesn't recover by the exchange. So, what about the Ledger and Trezor don't know clearly.
Not currencies but the crypto currency it self has the negative effect. You know that it is a virtual currency. By creating this in the economy the purchasing medium is increasing and finally leads to more inflation. So, there should be caution and strict regulation in the market so that no fake crypto is hovering nor be created. But, Bitcoin is a very sophisticated software which does not have any flaw and also completely avoid the double spending situation. So, the negative effect of the currencies are occurring because of the scam and the fake virtual coin, this like an Fake fiat paper currency.
