And thank you for ur help
I think a coin that is perfect and very profitable and promising only bitcoin only, because if you look at the condition of total supply bitcoin owned is very limited but it has a very high demand make the bitcoin gives the advantage that is very much if you hold it for the long haul.
No doubt bitcoin is the most established, strong and trusted crypto and with it everyone can hold it for long period with anticipation of getting a good profit. And it's the most safe to invest because we know how it moves and time to time people are getting their interest in it and invest. I would suggest to look for a coin that have a finite supply and have a high circulating supply so the value will surge eventually.
