First you need to decide to devirsifie your investmen.
For very long term project and it is strongest crypto currencies, i put my money on BTC 40%
For middle term project i will put my 30% money in to altcoin which already listed on exchanger and coinmarketcap.
For short term i put in my money in to ICO which i did due diligent on it. Like XSL Labs, Vulcan Forged, Citizen finance and student coin.
you share your investment in a good plan.
but for me, there is only one investment with long-term planning.
and the other is day trading. Planning too many investment assets can sometimes make us forget our plans when market conditions can make us panic.
