I found lot of traders who bought a special coin from many exchange site. Then few months they go for sleep and wake up after 5 years. So now what about your trade?
I have an account on several exchange sites, because they have different coin volumes. when I am interested in one coin I tend to see the volume in coinmarketcap and choose an exchange that has the largest volume, because in my opinion this is important considering the more transactions in the exchange. in a lot of transactions I just took a little profit because of value fluctuations in a few days, but for coin-coins that have a big community, it is more worthy for the long term.
