is better to have diversified investment (Ex : 1000 invest to 5 coin , 200 each ) or concentrated investment (1000 invest to 1 coin only ) ? Because I'm thinking that if i split the budget to multiple coin
First before any investment you must understand in what you are investing. Do you understand technology behind Bitcoin/any other coin? If not, you should, not in great detail but most important details. Then you would realize there is no 5 coins on the market, there is only one which is Bitcoin, all others are copy-paste with name changed. There is only one different coin which is Ethereum. So real question is, do you want invest in Bitcoin and Ethereum and you understand that Bitcoin hold value and Ethereum not because it have whole different design?
