I have a question.
What is better? To keep your coins on some Exchange site or to open wallets for each coin?
I would like to hear some advice. What are pros & cons of each option?
Thanks
A difficult question, here everyone decides for himself what he wants from the coin.
if I correctly understood the question, do you want to know, it's better to exchange different tokens into one coin or create a purse for each of the coins ...
1. Consider the option of transferring all coins and tokens into one, more weighty ...
Let's say you have 20 different tokens for some amount (say "N" of the etherium), you can exchange tokens for this eth, or you can keep them in coins. It all depends on the tokens, and on you. The tokens will jump in the price upside down (more often down), ask yourself if you are ready to hold tokens so that they grow in price, it can happen tomorrow, maybe in a week, a year or never at all, so the token may fall in value, or even generally depreciate ... From what it follows that your amount of "N" tokens also changes. This is a kind of game in which you do not know where the course will go, so it's up to you to keep tokens or exchange for ethereum and keep them on the eth, but remember that in the reverse order, you can exchange the ethereum for tokens. But do you need it ?!
2. Consider the option to keep all the tokens on different wallets and not to transfer them into one expensive coin. You need a lot of time (at first) to track the course of each of the coins, you must understand that the coin may fall tomorrow or it may rise, it needs to be tracked ... Of course, let's take Forex, for example, there teams of professional analysts can not predict the dollar ... one dollar only for a while, and you will need to track dozens of different coins, all alone. Of course, sometimes the expectation of yourself pays off and the coin you saved and continued to grow will bring a very good amount, and you will be happy, but read the forums, ask the Holders, I think that such a percentage of tokens is very low.
Following from this you decide what to do, do not take the advice of other people, it's luck. Someone is lucky, some do not, and it's better to spend more time and understand what's what, read various materials.
This is all my personal opinion, someone might disagree with me. I hope you will benefit from my answer if I understand your question correctly!
Good luck!
