Most Airdrops are scam, you may earn in airdrops but not all some tokens you earn will be a display in your wallet and there's nothing you can do unless you deposit money as your withdrawal mmfor the token you earn.

Woah! What a nice achievement in the forum which means there will be lots of users in here that can share their own expertise in cryptocurrency oe blockchain and it's advantage to beginners!
Let's start sharing now on what you learn in cryptoindustry by replying your knowledge below to motivate clueless users in here. I know some of us are experts already by now but don't forget where you started.

I'll start.

There are two most popular algorithms used in cryptocurrency:
First, is Sha-256 which is used in bitcoin
Second, is scrypt which is used in altcoins such as litecoin.

More infornation will be found in here especially for miners this information will be useful.

SCRYPT MINER

---

Crypto mining advances to greater heights. More and more users begin to discover its perks. As more altcoins are introduced, it becomes a more viable way of earning profits. Today, manufacturers produce equipment that makes the whole mining process faster and easier, called scrypt miner. These tools reduce power and improve mining efficiency. It is one of the many innovations that makes the process more attractive and rewarding.

One of the biggest differences between a scrypt miner and the SHA-256 is that scrypt relies on computing resources other than the processing unit itself. On the other hand, the latter does not. This makes it hard for scrypt-based systems to scale up and consume computing power because they would have to employ a relative amount of memory, which is costly.

The role of a SCRYPT MINER

---

The scrypt miner was first introduced with the emergence of Litecoin. Some of the benefits that draw the attention of a miner includes lower block times and ASIC resistance. It was implemented to prevent litecoins from being mined using GPU’s. However, it failed to prevent GPU miners from entering the network. Scrypt was initially made to serve as a backup service. It prevents attacks from happening.

BENEFITS OF A SCRYPT MINER

Meanwhile, miners commend it because it is GPU-friendly. A large portion of scrypt miners involves GPU miners as well. While it takes up more memory than its counterparts, the fact that it uses less energy makes it more attractive. With less electricity consumption, miners can get the most out of their earnings.

A scrypt miner also lessens the advantage of ASIC Bitcoin miners. It keeps the field level. It means that more miners have the chance to join the network. Anyone can contribute and make the most of their efforts.

Opinion ko lang to mga paps, kung ako ang tatanungin ok lang naman ako sa copy paste kung ang topic ay tungkol sa cryptocurrency at ang nag post makakasagot sa iba kung may tanong ang isang tao sa nagpost. Hindi naman masama kung mag share lang ng infomarmation basta nakakatulong lang sa ibang tao. Dapat din naman may source na nakalagay at huwag gawing sariling post ang kinopya na topic.

Mga kabayan ko, may thread ba dito kung saan makikita ang RANK REQUIREMENTS? Di ko kasi alam medyo nalilitohan pa ako sa altcoinstalks eh patulong naman.

Easy way to understand about your issue.
Bitcoin is bitcoin, a decentralized cryptocurrency.
Altcoin is altcoin, alternate coin/cryptocurrency that is base on bitcoin.
Let's make bitcoin and altcoin a human.

Karma is given by Sr. Members and above as an appreciation for the valuable contribution that you have made. Its normally a Thank / Punish button. If they feel like thanking you for your post, you get +Karma. If they punish you for violating forum rules /spamming, you get - Karma.
If you got more - Karma, you'll not be allowed to withdraw the tokens or participate in airdrops/Bounties. A recent announcement made by the admin shows that you can even exchange your Karma for ALTs.

I see, thank you for sharing the information of karma.  Pressing thanks will get +karma and punish for -karma right?.

Tokens are  utility that usually resides on top of another blochain but coins are alternative to bitcoin .

You are right but most tokens resides on ethereum network or as we call it ERC-20 tokens.
