Can anyone suggest me how the rate of these type of coins up-down?
There are several factors that affects the prices of cryptocurrency negatively and positively;
DEMAND AND SUPPLY - Shifts in cryptocurrency prices is due to the law of demand and supply changes. The price of an asset is dependent on the demand and supply of the said asset. Example, if there is high demand for a coin with low supply, the rate rises. If there is more supply than demand, the rate decreases.
MASS MEDIA/NEWS - Positive or negative reviews/analysis can also affect the rate of cryptocurrencies.
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?

IOTA
STEEM

Tezos.
HOWEVER, UNDERSTAND YOUR OWN RESEARCH AND CONCLUSION IS WHAT MATTERS DURING INVESTING.
