While investing, you must really take your time to do quality research and a proper market analysis so that you don't get too disappointed, and perhaps you also have to prepare your mind for it. Currently, I am not buying any altcoins because I still have a targeted amount of Bitcoin to accumulate and I don't want to get distracted by any altcoin. Although there are no top altcoins that I can't buy unless I have analysed the market and seen that there is zero possibility of making profit, if there is chance of profit, then I will buy the altcoin.
