For me I hold my tokens for about a months or even more and when the price goes up to 30% I withdraw it or either I get it or trade it to other tokens. But mostly I hold my tokens for the future even I bought newly tokens in a presale ICO.  

There are so many altcoins to be mention as long as you hold your coins for longer years there ia a possibility that you can get more profit. You can also check or ypdate on coinmarketcap and other sites and the more coins you have hold in the future its better.

I want to join this awesome great  project and good luck to the participants.

Yes,  of course I am afraid of the hackers because their mind is beyond our expectations they hack and they will get all the informations and even your profit. Some of the hackers are professionals on what they are doing system hacking and other stuff. You will loss all of your efforts once the hacker hack your account.

It is good to buy  BTC when the price is down when it is 30% cause its cheaper and its a chance to buy BTC when it isin low price.  Then wait for it when the price goes high you can hold it or you can trade it or you can buy other voins that has a cheaper price.

Yes,  you can do mining on your mobile phone and it depends what kind of phone are you using android or iOS if the specs of your phone is higher it can mine more rates but if your phone is a low specs it mines only low and slow rates.  But I don't like mining using mobile devices I prefer using PC computer or a highend laptop.

In my own opinion if I get a token that has already a price in the market I will sell it or either I will trade it.  But if the token or coins that I get have no price in the market I will surely hold it for a while and wait when it has a price in the exchange market.

Here's what you do if you're a newbie observe and always keep on reading about bitcoin, altcoin and you must know everything about blockchain. And when you want to join to a bounty campaign or any airdrop you need to rank up in bitcointalk.org so that you can join in a bounty. Always be resourceful all the time.

There is a lot of airdrops to find and to be joined like in telegram and in other social media site facebook and twitter. But always be aware of many fake and scam airdrops.

Bounty campaigns is getting better and becoming famous right now because of the higher percentage that you can get and its varies in how many participants joining. If the supply of the bounty is bigger the more the participants are joining it means the more the better and the stakes will be divided if how many participants are in there. 

There is a lot of good and promising ICO and you can determine it by reading their platform,  roadmap, and whitepaper then you will know if it is a good ICO to join.  Always be aware because there is a lot of ICO that scam.

This looks like a promising and awesome project. Hopefully this project will succeed in the future.  I will support this to the end. Best luck.

For me as of my own knowloedge about crypto markets and exchanges,  I've been trying a lot of it like etherdelta, forkdelta,  idex,  binance but I truly prefer the most friendly platform and easy to understand and the securities of your profit must be there. Centralize or decentralize platforms of exchange.

This is looks like an awesome airdrop project. Good job dev and good luck to all of the participants and let's bring this to the moon.

There are so many ICO's to be joined but watch for the scam one and make sure that the ICO has their own platforms and other information about their programs. So it is safe to participate in some ICO's and its up to you to decide and to whom trust.

Yes,  for me as a airdrop hunter and a holder of tokens this is been very good experience because I really like aidrop so much and it is very exciting fill up the forms and wait for your tokens without any pressure and hustle. More Airdrops to come in the future. ☺

I'm glad to join this airdrop and looking forward for the success in the future.  Good luck dev.

I think some of the countries they don't treat bitcoin as legal in many ways becauae of the benefit they can get.  And it depends in the country if they will legalize bitcoin as their currency but for now bitcoin is use in other countries.

Yes bitcoin is worth it when you invest it properly and when bitcoin pumps up you will be surprise.

Looks like a good and interesting project that can be better in the future. Gonna join this good luck for me.  Thanks dev
