Am really confused on the what to invest I need some clarification on which is the best now
There's no "best altcoin". Bitcoin is the best and for now all the altcoins are behind it.
If you want to invest you have to do your homework and if you want to do it right you better avoid "shortcuts".
Also don't invest based on people's advises on the internet. You don't know if they genuinely want to help or just advertise some coins they want to sell.
