In my opinion top ten altcoin to invest now is : ETH, DASH, LTC, WAVES, POWR, POLL, SALT, BCH, NEO and NXT. But will be great idea to trade this altcoin with BTC or ETH to increasing the amount of those altcoin, also because price of BTC and ETH strong up trend now. Just stay to trade in these altcoin and buy and sell just turn on that so I think will more safe than move to others altcoin.

In my opinion EtherDelta is 100% safe because this is decentralized exchange which we own the private key, just remember always login from bookmark link and save the private key in safe place and easy to access. But at the moment Ethereum network overload so trade in EtherDelta take along time for buy and sell and should be increasing the gas price.

These 2 coin in my opinion has strong in fundamental so will good idea to buy now for long term investment, but I think by different portfolio for example Bitcoin 70% portfolio and 30% for Litecoin. Bitcoin still able to going up to $50,000 in the longterm because as we know totally supply only 21 million and circulating supply only about 16 million but now many people around the world buying Bitcoin, in addition, even banks and other financial institutions also buy bitcoin for investment., and also many country regulated Bitcoin so the demand continue increasing.

Its hard to know when next pump will happen, we can only predict it. And next pump usually happen when the price on oversold area and long consolidation, buy it when you find this level and wait with patiently, so most likely the price will be pump and make profit.

In my opinion usually some coin will pump when in oversold area/cheap price and long consolidation, and then will easy to pump it so you need to learn about technical analysis.  And also the coin will pump cause some rumor, so will be important to learn about fundamental analysis too.

My opinion 1 BTC is huge already because you can turn it in to 10 times probably in a few amonth, but I think the most important thing than amount of capital is strategy, trading plan and risk management, we should be have experienced to manage the risk and to maximize the profit. Use technical and fundamental analysis and other more thing dont be greedy when on profit, always use trading plan so we will make big money by continue. But if you are still newbie much better start by $100 so when you loss not really effect with your psikilogis.

I use 4 exchange for my day trade, those is Poloniex, Bittrex, EtherDelta and Cryptopia. I use 4 exchange because I think will be more safe if we divide fund in to 4 if any happen with that exchange. But mostly I like is poloniex because the trading fee is smaller compared with the others. And for the charting i use Trading View site , this site is very well to learn about technical analysis because available many kind of indikator and the display is bright.

In my personalilty I made investment in Bitcoin 80% of total my money, and other 20% in fiat. And then from that 80% of Bitcoin i divide in to 2 portfolio, 70% of Bitcoin for long term investment and other 30% for day trading because day trade is more risky than hold Bitcoin but will be promising higher profit. By this portfolio and risk management in trading i hope i can increasing my money by continue.

To decide to sell when on profit usually I used daily chart and specify the overbought area and which level price of that crypto havebeen reached before, so not depend on the percentage but depend on price level area and charting because volatility of crypto so high so if decide to take profit by percentage the price could be go higher again so we miss the bigger profit.

I have also some altcoin but I trade it to get more profit, and also buy again more this altcoin when the price down because I know the price will rise again later. Litecoin has big future because this altcoin has strong team developer and all cryptocurrency community know this coin and in top ten ranking coinmarketcap that has big volume and marketcap . This coin also mineable and no premined just the same thing like Bitcoin so everyone can to participated to mine it.

You can start trade even by small amount like $50, and to start it you have to learn first about technical analysis, how to read the chart, understand about volume transaction and learn about the function of some indikator.  But the key of trading is buy lower and sell high, buy when the price oversold area and sell it when in the overbought area. Then other thing is learn about how to manage the risk, always patient to get cheap price and dont be greedy when taking profit.

I been in crypto market around 3 years ago when the price of Bitcoin was about $250, but at that time I was using Bitcoin to play HYIP, and the results were good but I sold my Bitcoin at that time when the price at about $ 500. I feel so sorry to sell it and now the price of Bitcoin reached more than $ 10,000. Now  I will more focus to increase my Bitcoin in day trade altcoin.

In my opinion many altcoin that has strong in fundamental and safe to invest in it, just like ETH, DASH, LTC, WAVES,NEO and new coin  that just now listed on the market that is Power Ledger. All these coin, I think has big potential and good in fundamental so the price will be increasing in the future. Choose altcoin that has unique project and the aim of the project that interesting and solved many problem so the community will be bigger and the price also will be going up.

They collected big money already, and ussualy by that amount this project will succes and continue entered to the market. In my opinion many ICO legit now and has working product that uniqe and interesting. Now we should spend more time and doing some research to find it, like learn about purpose of the project, what problem they want to be solved and know in detail basic personality of team founder. 

Can be but this is not easy and need long time maybe a few years, because the team founder of ETH,NEO,WAVES also consist of many professional team who also looking for new idea to more development their project. All can happen depending on the their working products that can attract many communities of cryptocurrency and provide many benefits and conveniences

There are several different with Bitcoin and Ethereum. One of that is In Ethereum the block time is set to 14 to 15 seconds compared to Bitcoins 10 minutes. This allows for faster transaction times for Ethereum, and Ethereum does this by using the Ghost protocol, but even so Bitcoin is still more popular than Ethereum.

In my opinion there are many cryptocurrency that has big potential, one of that is Ethereum, Dash,Litecoin,Waves. And if you would like to looking for other next big new cryptocurrency that just entered the market, I think POWR is has good chooice. POWR has strong in fundamental, their product is work already in some country like New Zealand, Australia and India. This project also consist of many team who professional in the field, and other more thing is POWR project supported by Australia Goverment.

Both is promising profit and has some risk, In my opinion if you have free more time, learn trading is will be great idea because trading promising high return if you already expert to analysis the market and also when you enable to control emotion. Use portfolio 80% holding Bitcoin and others 20% of Bitcoin for day trading will be good decision and good trading plan. Also learn other fundamental analysis and risk management by continue will be making consistent profit.

Kalau saya lebih suka Bitcoin itu seperti sekarang yang bersifat desentralisasi tanpa ada pihak dan orang yang bisa mengaturnya, karena memang sifat dasar Bitcoin adalah desentralisasi, mungkin yang bisa di atur adalah nantinya dapat atau tidaknya penggunaan Bitcoin sebagai transaksi dalam pembelian barang dan jasa di Indonesia, atau dengan kata lain menyaingi rupiah. Kalau efek baik buruknya tergantung apakah pemerintah mau melegalkan Bitcoin atau tidak.

Yes arbiratge also promising some profit but there are any risk too, the risk is when Bitcoin confirmation so long and the withdrawal fee from current exchange to others exchange also expensive. And also some exchange has rule to enable withdraw should be have verified account, so this is not efisien .
