When it comes to altcoin, it has to be what you are willing to risk and can afford to lose. If the amount you have and willing to invest into altcoins are not what you consider to forfeit to the market, then you should consider seeking other options of investment and if it’s solely cryptocurrency, I’ll advise you stick to investing in bitcoin as your main portfolio. Altcoins are not an investment that you can give yourself a targeted x’s of profits that you wish to have, they may go your away, or even go way above your way or not even go your way at all. On how risky it is and advised not to invest in them, they may still give you that big profit you ever wish for but make sure you’re risking what you can afford to lose.
