1) buy a Hardware wallet like Ledger Nano S or TREZOR and buy it directly from their website (not AMAZON, ebay etc...)
2) store your private keys (for coins that hardware wallet does not support) in a safe place (NOT on your device).
3) save websites url  on your  favourites and double check address .
4) use a good antivirus and updated OS

airdrops rewards are very low normally so there is no big effect of selling that coins.... there are some people that tries to cheat using multiaccounts but most of times they just waste their time and be banned....

for example I have someone that is using my email for every airdrop..... i Have to spent 2 minutes of my time joining telegram ICo channel and make him be banned from admin..

I prefer holding expecially if I believe in the project... but when I have tokens that worth more than 1000$ I usually sell half and hold the rest....

There are also good ICO to invest, but nowadays is very difficult to pick the right ones.... and time to look after everything is limited....

Be faithful man, good times will come again and your -70% probably will become a +xxx%..... crypto world is very volatile that's the reason everyone say not to invest more than you can afford to loose without problems...

it's almost impossible to predict which coin will increse much more than others.... for me the best way is to have a diverificated portfolio with the more commons coins and then a little percentage of new altcoins/tokens...

The only problem MEW had was with DNS google hacked some weeks ago..  but if you use metamask ot etherlockup chrome extensions you don't have any prolblems...

The first one and most serious is for sure this FORUM..then I think twitter and telegram are also 2 big Social Media with a strong crypto community...

It depends of what is your amont of money that you can spend in investments... usually is better not to invest more than 10% of your investments amont in crypto, so if you have more than 100k you can invest more than 10k without any problems...
