Veraciously speaking, when it comes to investment, there's no such thing as right time, 'coz there's no such thing as wrong time. It's always right to invest, and now, this very minute, as in now, is always the right time to do so. Speaking of which is good to invest in, I suggest you divide your capital in half. Invest half of it in bitcoin since it is the center coin, and the other half in altcoins, proportionately distributed. But be very cautious in choosing the right altcoins to invest in. I suggest you get only two to three coins you are adept of exploring, so that you can monitor its movement closely. Take into consideration also the supply, the marketcap and the team behind it.
