The use of some currency in illegal activities doesn't make it illegal.

Everything related to money and is a liquid asset will be used in illegal activities. But this doesn't mean that cryptocurrencies are illegal. If someone says so, try to make them understand what cryptocurrencies actually are and even if we ban cryptos, these illegal trades are never going to stop. There is always some other way.

A 30%+ rise in few days isn't drastic then what is?

Bitcoin went to $8k+ from $6k in few days. This is good enough a growth brought by ETF speculation. But yes this growth wasn't seen in altcoins which made the market bit dull. ETF speculation is expected to bring more growth near 16th Aug. Before the news, the pump is definite. But after it, the scenario will depend upon whether the ETF get launched or not. 

You wouldn't be asking that if you knew technical analysis. What to choose is dependent upon your proficiency with TA. If you are good at TA, you can have a diverse portfolio where some percentage is put for long term and some is used for day trading. Day trading is largely dependent upon TA whereas HODl is more sentiment dependent. TA can give a general idea of the long term trend which until now is quite bullish for cryptos.

Because they have certain intrinsic value other than speculated value because of their use in different areas. I doubt the point that they are pretty famous among investors. That certainly isn't a case, people do prefer diversified investment plan which usually includes certain percentage in gold/silver.

Recently I came across a news that investment in silver is declining steeply because people are shifting their interest to cryptocurrencies.

Then stop imagining and forget BTC.

If BTC ever touches $100-$500, the next moment you will $1 because such price dump can bring a panic in the community. It won't be healthy for anyone to spend and invest at that moment in BTC. Such a low price is likely to bring an end to crypto world unless the volume and the price has shifted from BTC to some other coin and that is the reason for dump.

Nothing can be said with certainty unless BTC crosses $8800 successfully which is the next resistance for BTC. Today it seems that BTC is losing volume to reach $8800 which was confirmed by a little correction at $8400. This means that BTC will remain at this level in accumulation stage to pump it through $8800. Once it is done, BTC can be announced as bullish as next resistance would be $10k.

In long term, it would be an altcoin with an actual utility and mass usage. But for short term, BTC will maintain its dominance because it is preferred the most when it comes tzo investing in cryptos. Also, launch of BTC ETF etc is going to boost the money inflow in BTC which will help it to maintain its dominance in the marketcap. No other altcoin has potential to beat Bitcoin in short term.

I highly doubt that because bounty hunters are anyway going to get some free tokens and most of them don't even value their tokens and sell immediately. I would say almost 80% of the bounty hunters don't even go through the project they are working for unless there is some special requirement to post about the project or make some tweets or post on social media.

ETH did rally a bit in the start along with BTC price appreciation. But that didn't signal at all towards a bullish rally of ETH. ETH is finding it hard to gain volume nowadays. Altcoins might start their bullish rally if BTC crosses $9k which in one way will confirm BTC bullish phase and will confirm it for altcoins and hence, money will start flowing in altcoins as well giving them the much needed pump.

I would say diversify if you have a good amount to invest. Put 30% in BTC, trade 40% in altcoins and invest 30% in ICO. This way you can hedge your risk and will maximize profit in the less risk possible. Never go all in single coin. Crytpocurrencies don't worth that much risk. Diversification is the best way possible to dodge the volatility in altcoins and get the best out of cryptos.

Every coin as for now follows bitcoin price trajectory. Bitcoin has undergone a decent pump today, other coins specially the large mcap ones also surged along with Bitcoin. ETH being the second largest mcap coin is highly dependent upon BTC price action as when investments start coming in BTC, it also flows towards othe rcins specially ETH. Thus, ETH price surge is already expected.

Virtual currency is becoming a new hot. Facebook is expected to bring their own cryptocurrency, Google might do the same. We are moving towards a cashless society and cryptocurrencies can be a medium to that. With many countries and companies already exploring the blockchain and cryptocurrencies, it won't be wrong to expect Google to come up with one sooner or later.

I definitely gonna look for a reason behind the price surge. If the surge is because of some news in coming future, then price is likely to grow up further before the actual happening of the news. If, price is up because of some rumor or exchange listing, it is better to leave your position from that coin as early as possible because with more people knowing, price goes down pretty badly. In case of a pump without a reason, it is always better to short the profit and exit.

As expected, market has slowly turned green now. Almost every coin including bitcoin has risen by 5% whereas coins like BCH have risen by 10%-12%.
This should reignite hopes in the heart of people who had given up. I feel people are very pessimistic and do not have patience to wait even for a short while. They only want to see their money increase and do not even want to wait for a couple of days or weeks. People should learn to be patient.

BTC is not expected to go below the $6k threshold because of the strong support it has there. Like last time if BTC goes below $6700, the lowest it can go is $6k. From that it is likely to bounce back. BTC is expected to go more down in coming weeks, this is what charts are depicting. If it goes below $6k then there will be a FUD and panic selling. Price is largely controlled by bulk holders. They take price down for buying opportunity. They won't play with the market at the risk of ruining it. So, price won't go below $6k unless there is some really market damaging news.

Market has been into prolonged bear cycle. It was expected to show some sign of recovery in the month of May and it did too but that didn't stay for long. I expect June to be the same that is in bear phase. July can show some sign of recovery which can extend till September. Right now chart and market trends are pointing towards more dump. But that wouldn't be so deep as to ruin the market. Volume is pretty less right now and hence, the market isn't able to recover from the bear phase.

So, you are searching for a coin which have potential to give 10x returns in a year long period. Coins under $1 is mostly preferred by traders and investors. Thus, such oins are best for high ROI. I would suggest you to go for a undervalued coin like REMME. They have working and a potential project which is in data security sector, many partnerships, active team and community. What more is needed to tell about the potential of a coin? REMME is a good invstment option available at this point.

Crypto market is highly sensitive to news and rumors. News do have an important impact on the price movement. But the action should be taken at early as possible as you stated. The simple declaration of the positive news brings an instant pump and one could cash out on that opportunity if the step taken is on time. If you come late at the party, it is better to not invest after 20%-30% rise because after that there is more chances of a dump.

Stop loss are always recommended. People lose more in trades by not investing in a right coin but because not cutting their losses at the right time. Crypto market is so unpredictable that you can't really make out the next market move because of high manipulation. Thus, having stop loss at place won't hurt you. If you think we already testing the bottom, you can go for a higher percentage stop loss.
