Cryptocurrencies go up and down as per usual. You seem to be really new here, so I suggest actually doing research first before actually throwing your money in.
Can anyone advice me reliable coins that has their own signup system with client area where i can purchase and store coins in my own client area in their website?
If you're not willing to do the research, don't invest. Investing based on other people's opinions is definitely not the way to go.
Also, with your description on what you're looking for, you're pretty much describing most of the centralized shitcoins we have right now.
