lesson one
dont be greedy
lesson two
dont invest hoping for 2x-10x of funds in any way
lesson three
invest small and get out fast at just 1-3% profit
basically if your going to throw your whole hoard into something and wait 6-12 months for the hope of a 200% profit. you are bound to loose faith, loose funds or make silly decisions like 'what if i leave it in a little longer'
instead if you break your hoard into 10 allotments. and only put a buy in at X and then put a sell in at x+3%
you can get orders filled quite often and repeat multiple times
if thet price does not raise by 3% but instead falls. thats ok. you got 9 allotments left. so you can wait until X-5% and put a buy in and then sell that for x-2% to still get 3% from that order
by doing this at 5% spread between orders. you will always have value to buy with even if the price dips by 50%.. and that does not happen very often
but the price swaying 3-6% does. so you can just rinse and repeat
all of them small 3% amounts soon add up. and over a year can be quite a bit
...
its better to just 'gamble' on the exchange price fluctuatons. much safer than gambling on new ICO/crapcoin projects.
stick with coins that have longevity and actual real life usage. not promises of usage but no endorsement from industries a crap coin pretends tobe linked to.
and lastly
DONT BE GREEDY
