My personal coins that are suitable for long investments are bitcoin, ethereum and bch
I believe at the end of the year the price will be higher than this month's price
i agree with bch, when bitcoin bull run started bch will follow and increasing in value i aslo believe on bitcoin etf that will get approved so i think bch and btc is good option to invest. I do recommend Xlm and Nem they will be big when more people using blockchain technology and also they do have a real project which still going on.
in my part i still believe in bitcoin, because bitcoin is the most amazing coin in crypto and I believe that bitcoin is the most popular coin so it is really hard to to be failed if we invest in bitcoin, because it will not easily fall into zero value due to the market demand and popularity. We are really secure in bitcoin and we can have an assurance to earn as long as we have patience.
