I am a newbie and would like to invest $1000 to start. I have read that I should put 40 percent into bitcoin and diversify the other 60 percent. I need opinions, advice, and anything from those with experience of positive value. 
To begin a bitcoin journey, $1000 is a respectable sum of money.Hope you can afford to lose this money while trying to invest in the bitcoin market, nevertheless. Although you are a newbie, and I don't know how experienced you are in the cryptocurrency market despite you are newbie. If you are a complete beginner, I would advise focusing exclusively on Bitcoin only and to avoid any altcoin investments for the time being because you might not be able to conduct adequate research on them. It is a good idea to diversify in order to reduce your risks, but failing to have a thorough understanding of the other side may result in a significant risk.
If I were you as a Newbie, I would invest the all $1,000 in bitcoin, but if I were to gamble in another way as a beginner, I would just invest 5% or 10% in alternative cryptocurrencies to put myself on the safe side. I'm not promising you a profit from Bitcoin, but I can guarantee you that the risk may not be as great as altcoins from my experience.
