That is the safest strategy but at the same time many people in the forum want to obtain big profits out of their investments and you cannot do that by following the safest path, there are also many other coins that are not as popular or as powerful as those two coins but that are still going to be here for a long time and that can give you great profits, you just need to buy them when their price is really cheap and since the market crashed at the beginning of the year almost all the coins in the market can be bought for a very cheap price.
