Cryptocurrency bitcoin ethereum siacoin ripple golem bitshares dogecoin digibyte stellar lumens IOTA

Hi everybody
I am new to the Cryptocurrency world but in the past few weeks i learned so much about it and i am currently mining ethereum and considering to invest some money in the growing currencies.
Since i can't invest a lot of money my idea is to buy currencies that currently are under one dollar and wait for sometime and see the reward.
I spent sometime reading reviews and watching youtube videos for experts to understand each type of currency and how it can rise even which companies or banks supporting it.
Here are my results :
*Ripple and Sia have the highest potential to become the next big thing after bitcoin and ethereum
1-Ripple currency is a medium for converting any currency instantly into any other one, without relying on a central exchange that is the main strength point of ripple
2-Sia is your decentralized cloud. Sia offers to store your data on the blockchain.

The advantages are: - your data is accessible only by you and does not depend on a large company (Amazon, Google, Apple ...)
- the storage cost is 10 times less (about $ 2 a month to store 1 TB compared to $ 23 a month at Amazon S3).
- your data is stored in many nodes of the network, you lose nothing in the event of failure of one of the storage places.
3-goelm , bitshares, dogecoin ,digibyte,basic attention token,stellar lumens, IOTA
All of these currencies have great potential to rise above the 1 to 10 dollars within months
so i am going to invest in each of these coins in the hopes that one or two become the next big things and if i lose the money it will be ok because no risk no fun and i am investing my mining ethereum anyway
what do you think of these coins and am i missing something ?
