Many buy bitcoins and altcoins, they wait when the price will rise and sell. What other ways do you know?
In my own opinion it is better to join any bounty campaigns or ICO although you need to find ways if that ICO you joined is scam or real. Their is a time that bitcoins and altcoins price high and low because it is flactuation but that is ICO is the other way to save and increase the capital of cryptocurrencies.
To do any such thing, you need to plan the things in the best possible manner and that you need to make some good strategy which can then help you in achieving all your goals which you have set up. You need to be very much careful while dealing with your coins and that you should sell them only at time when rates are higher and then you need to go for using all that money again into the crypto currencies but at time when the coins are cheaper.
having an big capital is an big advantage in this industry, you can buy many coins as you want and you feel that it can be do a good performance. but before you gain an high capital you need to save. so my suggestiin is, buy coins when the market are in color red like now and hold for just 3-4 months or when ber months is here
