With 10 bitcoin I'd think I'd play it safe and store 8. While 8 are stored and growing in value I'd have 2 left to play with. With the remaining 2 I would probably start trading and growing that. Whenever the 2 reaches 4 from trading I'd bank 2 again and repeat the cycle. If i'd lose the 2 then I'd stop trading. Need to set limits for yourself.
if you're lucky maybe you can grow 1000% on gambling? so I think that small funds allocated for something have high risk
Yeah if I have 10 btc in my wallet then I won't mind to go for gambling even with 1 btc as if luck favors me than I can really win big with 1 btc and even if I loose, rest 9 btc will take care of me.
