The bad part of the usage of the cryptocurrencies are it can be use in criminal and illegal activities.

 If you are not putting any alerts, any orders, basically any prevention system and just let your money stay like that and manually do everything, in the bitcoin world some stuff happens very very very quickly, you may end up losing a lot of money. Just to give a very simple example, what would happen if you buy bitcoin at 8k, just leave and do not put any stop loss and orders no alerts, basically nothing? The price could literally go down to 7k and you might be asleep at that moment. However if you are ready for such a thing and have things build in for you, you will just automatically get out before it reachest that low. Always be ready to everything in bitcoin world, even when you are asleep.

Lack of concentration in investments makes us poor and it makes us worried when the market falls and we lose Chance to sell high. People often get busy and don't pay attention to market changes so this kind of mistake can make a good investor poor for taking wrong decisions in investment and selling at panic is the worst one mistake, it's my opinion.

Yes investors will have to be careful about investing their coin as minor mistake can give lose to investors. Mostly coins are having low value so if people will invest in valueless coin they will later cry for having it and the panic selling is also a mistake that investors often do which make them poor for selling their coins at lowest price.

Bitcoin is the best and most trustable among all. All other crypto coins are not valuable and workable like Bitcoin. This is because of many reasons, one of the leading cause is the crime cases and frauds associate with these coins. Scammers use these coins for frauds as they cannot use Bitcoin due to its large value and huge security. If you want to avoid risks use Bitcoins other than all.

Very well said, Bitcoin is the safest among all in any category. Adopt Bitcoin for daily and long term both types of trading. All the other coins are not at stable position to work with them. May be with time they will gain improvement but still Bitcoin will remain best among all. you can also do this that make half of your investment in Bitcoin and the rest with some other coin the comparison will make you surprise.

Education is important, without education you can't make long term progress. Money is one of the most important things in our lives, and we earn money with our knowledge. With the knowledge, you will be able to earn, without it you can lose the money you have!
Cryptocurrencies are money, you can use them to pay for things, to have fun, to pay bills, or as an investment. Invest in education and you will have more chances to earn more money, without education you relay on yourself and your skills, which is better than to rely on luck.

Well said, some coins looks so promising even after ico/ieo and even gets listed on nice exchanges with good volumes only for the team to dump all their tokens caring less about what becomes of their supporters or community.
As much as experience is much needed to get involved in shitcoins, a little bit of luck is needed too because not all that glitters are gold even in this ecosysyem.

I have not experienced any from the point listed here, I lose some money picking the wrong coin to invest, that was when ICO is in better shape and almost any crowdfunding there are worth investing, I was to late investing on these highly potential coin most that I got are shitcoins.

All of these must be considered important. Backup key at the first place is one of the most important thing that you need to remember to make sure that all of your investment is safe. Creating a weak password should be avoided as much as possible cause it leads you to higher risk of being hacked. Trusting anyone that you just met and making a transaction with them can also be considered as a huge mistake in cryptocurrency cause it will definitely lead you to possible frauds and risks that will consume all of your current investments.
