The best time to buy Ethereum is the price in the range of $ 120-180,but now the purchase can also bring profit in the future as the market will still turn in the direction of growth ,we have to wait.
To date, all crushed and Airdrops and Bounties. Many Airdrops distribute coins which are not on the exchanges of crypto-currencies and only clutter the wallet without bringing any benefit,the peak of relatively honest Airdrops and Bounties came at the end of 2017 and the beginning of 2018 when it was really possible to make a profit,although today remain popular bounty hunters.All full wallets!
I really want to hope that the world will soon change its mind about cryptocurrencies and Blockchain and cryptocurrency will be a revolution of our days in the world of electronic money and cryptocurrency will become a world currency,I really want it.
This is my opinion - in the long term, I can assume that such coins will grow ETC,ADA, NEO,LTC,WAVES,,EOS, and the impact of Blockchain technology will make our whole world beautiful.
