The reasons for changes in the price rate of any crypto currency can be summarized as changes in the balance of supply and demand in the market -
The reasons for the changes in the balance of supply and demand can be within the market:  when large players influence the price or cross-influences: when investors transfer their funds from altcoin to bitcoin and their balance is violated. Also, external factors, such as attempts to regulate crypto by countries and also negative news about the vulnerability of any crypto currency or the hacking of exchanges, and so on.

Баунти останутся в нынешней форме, пока они поддерживают привлечение средств в проекты, пока им нет альтернативы. Может в будущем и появятся другие маркетинговые кампании и новые правила но это будет не скоро.

I would add a large hard card to this list, because teams often set unrealistic goals, and all who wanted to would have bought the token on the ICO, and then, when they gets listed to the exchange, people do not want to buy them.

Does this project have any legal obstacles for listing on normal exchanges? I think they could afford at least Kucoin and it would be a penny for them compared to the money they collected, and do they really need that much money to create a project? It was about $ 100 million, right?

Несмотря на многочисленные скандалы связанные мошенничеством на ICO продолжают выходить новые проекты, и Россия за прошлый год заняла четвертое место среди крупнейших ICO по объему привлеченного капитала.

A lot of ICO is being created just to benefit the creators of the project, so often after the tokens go to the exchange the prices for them quickly fall. Sometimes this happens even before the bounties get their reward, so bounty members often sell their tokens immediately after they receive it to get some kind of benefit.

It's good that Switzerland see the potential that blockchain technology and crypto currency has, the more such positive news the sooner the market of crypto currency will recover.

According to experts, investments in ICO last year were profitable, and if investors invested in each ICO, regardless of whether it was fraudulent or not, the return on investment would increase 13.2 times. I think this year experienced investors will be able to get their profit.

The cost of bitcoin fell because the price was heavily inflated and grew due to the constant connection of new investors. Then, due to market manipulation, negative news and the outflow of investment, the price dropped to today's level.

While there will be people's interest in crypto-currencies, new ICOs will come out, because this is one way to raise investor’s money for new projects.

Криптовалюты появились после мирового финансового кризиса, так как было недоверие к банкам и правительствам и это послужило хорошим поводом для создания денег которые не контролируются государствами. Сейчас интерес к криптовалютам стал меньше, криптовалюты переживают не лучшее время и если случится еще один кризис то возможно они еще сильнее упадут в цене.

Crypto-currencies are not backed up in any way, unlike fiat money, which has a stable value due to the countries to which it belongs. The money of many countries is also not worth the price that is given for them, everything is built on trust - while the country is trusted, their monetary unit is afloat, and with the crypto currency, while there is investor confidence, it is priced.

The Crypto currency has not yet become so widespread in the society, that’s why it continues to need banks and governments. Even if a decentralized era begins, the government will still remain.

There are many ways for money laundering, and crypto currency is only one of these ways, and it is not very reliable because of his volatility. Probably blaming crypto currency for money laundering is just a way to discredit it, because it can greatly affect the money in the future.

Цену на криптовалюту формирует сообщество, чем выгоднее будет вести расчеты в  какой нибудь отдельно взятой востребованной криптовалюте тем выше на нее будет цена.

People believed in crypto because the prices for the crypto currency were raised and gave many a good chance to earn, so everyone wants to repeat this, if not this - than next year,  and hope for the best.

Usually the longer you take part in the bounty campaign the more steaks can be earned and, accordingly, the reward will be greater. But if you participate in the campaign which lasts six months, then during the same time you can participate in three bounties which will go for 2 months and get a large reward.

Bitcoin took the leading place because he entered first in the market and acts as a benchmark for other coin prices. But the main task of the crypto currency is to ensure quick and safe circulation of funds and not to increase capitalization, and if the market is more interested in a currency that is more convenient and functional than bitcoin, then maybe this coin can lead in the future.

I hope that in three years the crypto currency will be more in demand than now, strong volatility will stop due to large capitalization and to swing the market for profit will be more difficult.

I think the mining of bitcoin and ether will stop being profitable after some time, since the complexity of mining will increase significantly, but I think other crypto-currencies will come that can be mined.
