Welcome to the crypto world. Regardless of the amount, it is important to start.
Regardless of the amount you say… i think $110 is a good enough amount for a start. At least, this is someone that just started earning 5 figures for a pay grade even though the user didn’t specify on what currency and having to use $110 out of it to buy Bitcoin is a good place to start.
Hope the user gets to continue and more importantly, learn how to secure what you’ve gotten, not going about to look out for means to multiply the coin by trying to stake it on some platform, may be join in a cloud mining or perhaps trade it,,, these are always a tempting option but, you just might loss your coin in the process.
As you learn, learn security too, it’s very important to not break faith in the system.
$110 is good amount for a beginner to start with, might be he has been saving some funds for a while and he has bought some Bitcoin with it, I just hope he can continue buying such a decent amount every month.
The OP is not sure if the exchange his Bitcoin is are secure that's why he's asking but since then he hasn't say a word about how he's going around with he's investment, if he has moved it to a more secured wallet like electrum.
