If you had 10000$ where would you invest it? I'm hoping for 10x in about 2 years, how would you personally split that money? There are so many altcoins that I dont know which to pick, I remember the top 5 altcoins from years ago and now they are all gone, so should I only invest in BTC end ETH or others like NEO, ADA and EOS?
You need to divide that into multiple investment you do not need to do all in in 1 or 2 coins, i agree that you need to have bitcoin and eth but much better to buy 5 or more altcoin that you know have potential to give you a profit to achieved your target income.
You have to find the potential coin. I also suggest that you could buy hardware for mining. That will be good to have generator for you to continue have bitcoin. Diversifying an investment in many coins can help to gain good. It is also good to put some on real state asset like land and housings which can have good value in the future.
