I'm using Metamask for my ether add,so far I haven't experienced getting hacked and I use different wallet address if I want to join a bounty or trade my token in etherdelta or idex.I also have a different trading accounts secured with 2fa .And the important part is that I keep my private key and password somewhere safe,not on my laptop of cellphone.
If you want to have huge profit come back a year or two...Profit wont come for a couple of months specially if the project is new..Just learn how to wait..keep supporting the project you have invested and be updated on their development not on the price...
In our Group chat majority are girls doing bounties,airdrops and trading. Some are already managing bounties and others are telegram admins of a project...And its fun ...
I think eth is one of the most used crypto cause most ICO's are using ETH payments.Ethereum is just experiencing ups and downs just like other crypto, the price may drop but it will never die.It will recover in time for ETH platform has lots of potential to grow more.
We are holding our altcoins because we believe and trust the platform that it will give us a great profit, maybe not now but there's a great reward for those who hold a coin with great potential.
If you think the platform is great hold it for 2-3 years I'm sure you'll gain profits.In joining ICO you should think for a long term profit not because its already out in the market you can already gain profits.It will dip more in the next few months after it hit an exchanger so you must not panic..It will naturally grow once the market recover.
