No matter how many times they kill it, they will  go back to life because it is the new revolution of money. As long as there are Good government like Japanese Government that hates corruption, Cryptocurrency will triumph. There are already enough tax that they collect in every government/country, the only problem is how they use it.

 I think the bitcoin will still be the winner because eth is just altcoin that comes after btc.
indeed eth has made a very significant development every year

The coin who have potential to increase like bitcoin is probably ethereum because for sure the price of the ethereum will increase more in the future and if that happen most of the people who have ethereum in their wallet can earn a lot fo profit aftet few years for sure the money who are invested to ethereum will grow and you will harvest for your future.

BTC is the only other real coin that I like right now given the state of the market. I do also like one other coin but I don't have nearly as much confidence in it as I do bitcoin that is why I have been reducing exposure last couple months.

If the coin i bought has a promising future and have a solid project i usually get my initial investment if the price is already at 4X the price i bought and the rest are for trading if there is  sudden pump i will sell it and accumulate again once the price gets dumps but it depends on the news and updates of the specific coin.

Ethereum is not Scam but there is one fact about which all investors need to know. Vitalik Buterin Geek and him not is important the price Ethereum. if there is a choice between price and technology it will choose the technology.

For now, no one knows when icos might die but it all depends on what happens to the market in general
