I prefer bitcoin, because bitcoin has a larger community and the supply of coins is limited with a maximum supply of 21 million coins. But on another side, i also like ethereum because of the smart contract that has the potential to provide huge profits in the future. You can see the bitcoin and eth rank on the market, these two coins are equally potential as long-term investments. To buy coins depends on our capital, bitcoin investment requires more initial capital than eth, one of them by the fee of a transaction.

This is not about the right time to buy and sell the coins that you want. But this is about an analysis that you have to apply and assessing the potential of coins will be more valuable in the future. Basically, you have to apply to buy when the price is low and sell it when the price is high. You can see it first from the price chart that is viewed based on time series, it can help your analysis to determine the right time to buy coins.

No, cryptocurrency won't waste my time if we analyze price movements first. For me bitcoin is a very valuable long-term investment. I have a lot of time to be able to learn about cryptocurrency investments such as bitcoin, altcoin, ICO projects using fundamental analysis. I don't think this will waste my time because crypto's income is not my fixed income.

That is not a good idea and your friend's expectations are too high can predict the price of bitcoin in the future. As we know bitcoin or digital assets always fluctuate and the price stability is very low. I suggest that your friends learn first about tips and tricks for investing in cryptocurrency. But if your friend believes can collect bitcoin in a fast time and give more profits that exceed his expectations, i think this is the right decision.

Leaving bitcoin means we eliminate our valuable assets. To find out how bitcoin works, we should first know what is blockchain technology and smart-contract. With the unique peer-to-peer network, it works very fast compared to real transactions and no one can control it other than demand and supply in the market. Bitcoin is the most popular and preferred coin by investors. In fact, in the past few years, bitcoin can show itself with an increase in the price of coins that is too far from what people think.

Secara singkatnya dalam menganalisa ICO yang berpotensi untuk dijadikan investasi terdapat pada analisa mendasarnya. Teman-teman juga sudah mengetahui analisa tersebut dan saya rasa sudah banyak thread/post yang menjelaskannya. Seperti : website/whitepaper, jejaring sosial, legalitas, produk, dan lain sebagainya.
Dalam tahap pembelajaran, ada satu thread yang menambah pengetahuan saya dalam menganalisa ICO untuk berinvestasi, yaitu : Tips dan trik untuk membedakan proyek ICO yg memiliki potensi baik dan scam. dan semoga bisa membantu menjawab pertanyaan mas/mbak.

Thank you for the news of the showmebiz development. We are very proud to have been a part of the showmebiz community. This is the best bounty that i've ever got because the team is very solid, have a good strategy to keeps expocoin prices stable on the stock market. Success for the showmebiz team.

Saya setuju karena secara teknisnya kita tidak perlu mengeluarkan modal awal (uang) dalam mengerjakan tugas bounty. Kembali ke konsep dasarnya yang menyatakan bounty hunter adalah sebuah jasa perorangan untuk mempromosikan project ICO yang berlangsung. Tim pengembang ICO membutuhkan pihak ketiga untuk mempromosikan project mereka dengan memberikan imbalan pada tahap akhir promosi penjualan.
Sama halnya dengan jasa marketing di dunia nyata yang membutuhkan item-item yang dirangkul oleh TS, cuma bedanya pada bounty hunter kita melakukan promosi pada wadah digital/yang berbaur online untuk menarik kostumer/investor pada project ICO yang kita ikuti.
Untuk kesimpulan TS, sepenuhnya saya sangat setuju dengan mengharuskan "memilih project yang legit" dalam tanda kutip mengharuskan menganalisa terlebih dahulu project yang akan diikuti.
