I don't think it is advisable to invest all your money in ethereum, only invest with money you can afford to loose. Don't use all you have in your savings to investing in crypto. It is advisable to always save for the raining day, should incase a problem arise you will have something to fall back on.

I think social media is one way to promote a project it is very effective. It helps to create awareness and enlightens people who do not have an idea of crypto, by so doing, you give them a knowledge about it especially when they read more about the scheme and they will decide if it is profitable or not.

I think crypto cannot end because it has so many advantages other than it's disadvantages and that is the part which our government have refused to see.
It only needs you to really take time to understand what crypto is all about and know all types of crypto and be sure of the ones to invest in, it also needs you to be alert of scams and theft.

I think buying newly listed coin is a game of profit and loss because in business, you do not expect it to yield profit immediately. You buying now may worth really more than your expectations and the reverse might be the case. you can buy now and as the price increases, your coin increases and otherwise.
